For this purpose, we created a voice database that contains different phrases in two languages, English and Spanish, for men and women. As a classifier, the LIRA (Limited Receptive Area) grayscale neural classifier was selected. The LIRA grayscale neural classifier was developed for image recognition tasks and demonstrated good results. Therefore, we decided to develop a recognition system using this classifier for voice recognition. From a specific set of speakers, we can recognize the speaker’s voice. For this purpose, the system uses spectrograms of the voice signals as input to the system, extracts the characteristics and identifies the speaker. The results are described and analyzed in this article. The classifier can be used for speaker identification in security system or smart buildings for different types of intelligent devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extreme%20learning" title="extreme learning">extreme learning</a>, <a href="https://publications.waset.org/abstracts/search?q=LIRA%20neural%20classifier" title=" LIRA neural classifier"> LIRA neural classifier</a>, <a href="https://publications.waset.org/abstracts/search?q=speaker%20identification" title=" speaker identification"> speaker identification</a>, <a href="https://publications.waset.org/abstracts/search?q=voice%20recognition" title=" voice recognition"> voice recognition</a> </p> <a href="https://publications.waset.org/abstracts/112384/speaker-recognition-using-lira-neural-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112384.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2134</span> Comparing Emotion Recognition from Voice and Facial Data Using Time Invariant Features</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vesna%20Kirandziska">Vesna Kirandziska</a>, <a href="https://publications.waset.org/abstracts/search?q=Nevena%20Ackovska"> Nevena Ackovska</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Madevska%20Bogdanova"> Ana Madevska Bogdanova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problem of emotion recognition is a challenging problem. It is still an open problem from the aspect of both intelligent systems and psychology. In this paper, both voice features and facial features are used for building an emotion recognition system. A Support Vector Machine classifiers are built by using raw data from video recordings. In this paper, the results obtained for the emotion recognition are given, and a discussion about the validity and the expressiveness of different emotions is presented. A comparison between the classifiers build from facial data only, voice data only and from the combination of both data is made here. The need for a better combination of the information from facial expression and voice data is argued. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emotion%20recognition" title="emotion recognition">emotion recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=facial%20recognition" title=" facial recognition"> facial recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=signal%20processing" title=" signal processing"> signal processing</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a> </p> <a href="https://publications.waset.org/abstracts/42384/comparing-emotion-recognition-from-voice-and-facial-data-using-time-invariant-features" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42384.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">316</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2133</span> Advanced Mouse Cursor Control and Speech Recognition Module</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prasad%20Kalagura">Prasad Kalagura</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20Veeresh%20kumar"> B.

This paper proposes a Deep Learning model that can classify the user responses as inputs for an interactive voice response system. A dataset with Wolof language words ‘yes’ and ‘no’ is collected as audio recordings. A two stage Data Augmentation approach is adopted for enhancing the dataset size required by the deep neural network. Data preprocessing and feature engineering with Mel-Frequency Cepstral Coefficients are implemented. Convolutional Neural Networks (CNNs) have proven to be very powerful in image classification and are promising for audio processing when sounds are transformed into spectra. For performing voice response classification, the recordings are transformed into sound frequency feature spectra and then applied image classification methodology using a deep CNN model. The inference model of this trained and reusable Wolof voice response recognition system can be integrated with many applications associated with both web and mobile platforms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automatic%20speech%20recognition" title="automatic speech recognition">automatic speech recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=interactive%20voice%20response" title=" interactive voice response"> interactive voice response</a>, <a href="https://publications.waset.org/abstracts/search?q=voice%20response%20recognition" title=" voice response recognition"> voice response recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=wolof%20word%20classification" title=" wolof word classification"> wolof word classification</a> </p> <a href="https://publications.waset.org/abstracts/150305/wolof-voice-response-recognition-system-a-deep-learning-model-for-wolof-audio-classification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150305.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">117</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2131</span> Integrated Gesture and Voice-Activated Mouse Control System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dev%20Pratap%20Singh">Dev Pratap Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Harshika%20Hasija"> Harshika Hasija</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashwini%20S."> Ashwini S.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The project aims to provide a touchless, intuitive interface for human-computer interaction, enabling users to control their computers using hand gestures and voice commands.

The biggest problem arises when the cases involving disguised voice samples come across for the purpose of examination and identification. Such type of voice samples of anonymous callers is frequently encountered in crimes involving kidnapping, blackmailing, hoax extortion and many more, where the speaker makes a deliberate effort to manipulate their natural voice in order to conceal their identity due to the fear of being caught. Voice disguise causes serious damage to the natural vocal parameters of the speakers and thus complicates the process of identification. The sole objective of this doctoral project is to find out the possibility of rendering definite opinions in cases involving disguised speech by experimentally determining the effects of different disguise forms on personal identification and percentage rate of speaker recognition for various voice disguise techniques such as raised pitch, lower pitch, increased nasality, covering the mouth, constricting tract, obstacle in mouth etc by analyzing and comparing the amount of phonetic and acoustic variation in of artificial (disguised) and natural sample of an individual, by auditory as well as spectrographic analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forensic" title="forensic">forensic</a>, <a href="https://publications.waset.org/abstracts/search?q=speaker%20recognition" title=" speaker recognition"> speaker recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=voice" title=" voice"> voice</a>, <a href="https://publications.waset.org/abstracts/search?q=speech" title=" speech"> speech</a>, <a href="https://publications.waset.org/abstracts/search?q=disguise" title=" disguise"> disguise</a>, <a href="https://publications.waset.org/abstracts/search?q=identification" title=" identification"> identification</a> </p> <a href="https://publications.waset.org/abstracts/47439/acoustic-analysis-for-comparison-and-identification-of-normal-and-disguised-speech-of-individuals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47439.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2127</span> Gesture-Controlled Interface Using Computer Vision and Python</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vedant%20Vardhan%20Rathour">Vedant Vardhan Rathour</a>, <a href="https://publications.waset.org/abstracts/search?q=Anant%20Agrawal"> Anant Agrawal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The project aims to provide a touchless, intuitive interface for human-computer interaction, enabling users to control their computer using hand gestures and voice commands.

Unlike other biometric evidence, for example, fingerprints and retina scans, etc., voice can be easily changed or mimicked. The present paper talks about how the inhalation of helium and sulfur hexafluoride (SF6) gas affects the voice formant frequencies that are the resonant frequencies of the vocal tract. Helium gas is low-density gas; hence, the voice travels with a higher speed than that of air. On the other side in SF6 gas voice travels with lower speed than that of air due to its higher density. These results in decreasing the resonant frequencies of voice in helium and increasing in SF6. Results are presented with the help of Praat software, which is used for voice analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=voice%20formants" title="voice formants">voice formants</a>, <a href="https://publications.waset.org/abstracts/search?q=helium" title=" helium"> helium</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfur%20hexafluoride" title=" sulfur hexafluoride"> sulfur hexafluoride</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20inhalation" title=" gas inhalation"> gas inhalation</a> </p> <a href="https://publications.waset.org/abstracts/115121/effect-of-helium-and-sulfur-hexafluoride-gas-inhalation-on-voice-resonances" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115121.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2125</span> Environmentally Adaptive Acoustic Echo Suppression for Barge-in Speech Recognition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jong%20Han%20Joo">Jong Han Joo</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung%20Hoon%20Lee"> Jung Hoon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Sun%20Kim"> Young Sun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Young%20Kang"> Jae Young Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Ho%20Choi"> Seung Ho Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we propose a novel technique for acoustic echo suppression (AES) during speech recognition under barge-in conditions. Conventional AES methods based on spectral subtraction apply fixed weights to the estimated echo path transfer function (EPTF) at the current signal segment and to the EPTF estimated until the previous time interval. We propose a new approach that adaptively updates weight parameters in response to abrupt changes in the acoustic environment due to background noises or double-talk. Furthermore, we devised a voice activity detector and an initial time-delay estimator for barge-in speech recognition in communication networks. The initial time delay is estimated using log-spectral distance measure, as well as cross-correlation coefficients. The experimental results show that the developed techniques can be successfully applied in barge-in speech recognition systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20echo%20suppression" title="acoustic echo suppression">acoustic echo suppression</a>, <a href="https://publications.waset.org/abstracts/search?q=barge-in" title=" barge-in"> barge-in</a>, <a href="https://publications.waset.org/abstracts/search?q=speech%20recognition" title=" speech recognition"> speech recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=echo%20path%20transfer%20function" title=" echo path transfer function"> echo path transfer function</a>, <a href="https://publications.waset.org/abstracts/search?q=initial%20delay%20estimator" title=" initial delay estimator"> initial delay estimator</a>, <a href="https://publications.waset.org/abstracts/search?q=voice%20activity%20detector" title=" voice activity detector"> voice activity detector</a> </p> <a href="https://publications.waset.org/abstracts/17151/environmentally-adaptive-acoustic-echo-suppression-for-barge-in-speech-recognition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17151.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2124</span> Features Dimensionality Reduction and Multi-Dimensional Voice-Processing Program to Parkinson Disease Discrimination</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Djamila%20Meghraoui">Djamila Meghraoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Bachir%20Boudraa"> Bachir Boudraa</a>, <a href="https://publications.waset.org/abstracts/search?q=Thouraya%20Meksen"> Thouraya Meksen</a>, <a href="https://publications.waset.org/abstracts/search?q=M.Boudraa"> M.Boudraa </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Parkinson's disease is a pathology that involves characteristic perturbations in patients’ voices. This paper describes a proposed method that aims to diagnose persons with Parkinson (PWP) by analyzing on line their voices signals. First, Thresholds signals alterations are determined by the Multi-Dimensional Voice Program (MDVP). Principal Analysis (PCA) is exploited to select the main voice principal componentsthat are significantly affected in a patient. The decision phase is realized by a Mul-tinomial Bayes (MNB) Classifier that categorizes an analyzed voice in one of the two resulting classes: healthy or PWP. The prediction accuracy achieved reaching 98.8% is very promising. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parkinson%E2%80%99s%20disease%20recognition" title="Parkinson’s disease recognition">Parkinson’s disease recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=PCA" title=" PCA"> PCA</a>, <a href="https://publications.waset.org/abstracts/search?q=MDVP" title=" MDVP"> MDVP</a>, <a href="https://publications.waset.org/abstracts/search?q=multinomial%20Naive%20Bayes" title=" multinomial Naive Bayes"> multinomial Naive Bayes</a> </p> <a href="https://publications.waset.org/abstracts/59181/features-dimensionality-reduction-and-multi-dimensional-voice-processing-program-to-parkinson-disease-discrimination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59181.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">278</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2123</span> Identity Verification Based on Multimodal Machine Learning on Red Green Blue (RGB) Red Green Blue-Depth (RGB-D) Voice Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=LuoJiaoyang">LuoJiaoyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Hongyang"> Yu Hongyang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we experimented with a new approach to multimodal identification using RGB, RGB-D and voice data.

We believe that the data of different modalities can enhance the effect of the model through mutual reinforcement. We try to increase the three modalities on the basis of the dual modalities and try to improve the effectiveness of the network by increasing the number of modalities. We also implemented the single-modal identification system separately, tested the data of these different modalities under clean and noisy conditions, and compared the performance with the multimodal model. In the process of designing the multimodal model, we tried a variety of different fusion strategies and finally chose the fusion method with the best performance. The experimental results show that the performance of the multimodal system is better than that of the single modality, especially in dealing with noise, and the multimodal system can achieve an average improvement of 5%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multimodal" title="multimodal">multimodal</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20modalities" title=" three modalities"> three modalities</a>, <a href="https://publications.waset.org/abstracts/search?q=RGB-D" title=" RGB-D"> RGB-D</a>, <a href="https://publications.waset.org/abstracts/search?q=identity%20verification" title=" identity verification"> identity verification</a> </p> <a href="https://publications.waset.org/abstracts/163265/identity-verification-based-on-multimodal-machine-learning-on-red-green-blue-rgb-red-green-blue-depth-rgb-d-voice-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163265.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2122</span> Comparing Sounds of the Singing Voice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christel%20Elisabeth%20Bonin">Christel Elisabeth Bonin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This experiment aims at showing that classical singing and belting have both different singing qualities, but singing with a speaking voice has no singing quality. For this purpose, a singing female voice was recorded on four different tone pitches, singing the vowel ‘a’ by using 3 different kinds of singing - classical trained voice, belting voice and speaking voice. The recordings have been entered in the Software Praat. Then the formants of each recorded tone were compared to each other and put in relationship to the singer’s formant. The visible results are taken as an indicator of comparable sound qualities of a classical trained female voice and a belting female voice concerning the concentration of overtones in F1 to F5 and a lack of sound quality in the speaking voice for singing purpose. The results also show that classical singing and belting are both valuable vocal techniques for singing due to their richness of overtones and that belting is not comparable to shouting or screaming. Singing with a speaking voice in contrast should not be called singing due to the lack of overtones which means by definition that there is no musical tone. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=formants" title="formants">formants</a>, <a href="https://publications.waset.org/abstracts/search?q=overtone" title=" overtone"> overtone</a>, <a href="https://publications.waset.org/abstracts/search?q=singer%E2%80%99s%20formant" title=" singer’s formant"> singer’s formant</a>, <a href="https://publications.waset.org/abstracts/search?q=singing%20voice" title=" singing voice"> singing voice</a>, <a href="https://publications.waset.org/abstracts/search?q=belting" title=" belting"> belting</a>, <a href="https://publications.waset.org/abstracts/search?q=classical%20singing" title=" classical singing"> classical singing</a>, <a href="https://publications.waset.org/abstracts/search?q=singing%20with%20the%20speaking%20voice" title=" singing with the speaking voice"> singing with the speaking voice</a> </p> <a href="https://publications.waset.org/abstracts/41946/comparing-sounds-of-the-singing-voice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41946.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">329</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2121</span> Biometric Recognition Techniques: A Survey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shabir%20Ahmad%20Sofi">Shabir Ahmad Sofi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shubham%20Aggarwal"> Shubham Aggarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanyam%20Singhal"> Sanyam Singhal</a>, <a href="https://publications.waset.org/abstracts/search?q=Roohie%20Naaz"> Roohie Naaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biometric recognition refers to an automatic recognition of individuals based on a feature vector(s) derived from their physiological and/or behavioral characteristic. Biometric recognition systems should provide a reliable personal recognition schemes to either confirm or determine the identity of an individual. These features are used to provide an authentication for computer based security systems. Applications of such a system include computer systems security, secure electronic banking, mobile phones, credit cards, secure access to buildings, health and social services. By using biometrics a person could be identified based on 'who she/he is' rather than 'what she/he has' (card, token, key) or 'what she/he knows' (password, PIN).

Voice restoration plays an important role in social activities and communication. Several techniques have been developed for voice restoration and reported to improve the life quality. However, the rehabilitation program for voice reconstruction by using the ileocolon flap still unclear. A retrospective study was done, and the patients' data were drawn from the medical records between 2010 and 2016 who underwent voice reconstruction by ileocolon flap after laryngectomy. All of them were trained to swallow first; then, the voice rehabilitation was started. The outcome of voice was evaluated after 6 months using the 4-point scoring scale. In our result, 9.8% patients could give very clear voice so everyone could understand their speech, 61% patients could be understood well by families and friends, 20.2% patients could only talk with family, and 9% patients had difficulty to be understood. Moreover, the 57% patients did not need a second surgery, but in 43% patients voice was made clear by a second surgery. In this study, we demonstrated that the rehabilitation program after voice reconstruction with ileocolon flap for post-laryngectomy patients is important because the anatomical structure is different from the normal larynx. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=post-laryngectomy" title="post-laryngectomy">post-laryngectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=ileocolon%20flap" title=" ileocolon flap"> ileocolon flap</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a>, <a href="https://publications.waset.org/abstracts/search?q=voice%20reconstruction" title=" voice reconstruction"> voice reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/87060/the-voice-rehabilitation-program-following-ileocolon-flap-transfer-for-voice-reconstruction-after-laryngectomy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87060.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2119</span> Patient-Friendly Hand Gesture Recognition Using AI</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Prabhu">K.

In this AI-based hand recognition project, NodeMCU is used for the control action of the relay, and it is connected to the firebase for storing the value in the cloud and is interfaced with the python code via raspberry pi. For three hand gestures, a voice clip is added for intimation to the attendee. This is done with the help of Google’s text to speech and the inbuilt audio file option in the raspberry pi 4.

(i) The first system is based on a support vector machine (SVM), which was widely used in voice signal processing with the aim of speaker recognition involving verifying the identity of the speaker based on its voice characteristics, and (ii) the second is based on Gaussian Mixture Model (GMM) and Universal Background Model (UBM) to combine different functions from different resources to implement the SVM based. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=speaker%20verification" title="speaker verification">speaker verification</a>, <a href="https://publications.waset.org/abstracts/search?q=text-independent" title=" text-independent"> text-independent</a>, <a href="https://publications.waset.org/abstracts/search?q=support%20vector%20machine" title=" support vector machine"> support vector machine</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaussian%20mixture%20model" title=" Gaussian mixture model"> Gaussian mixture model</a>, <a href="https://publications.waset.org/abstracts/search?q=cepstral%20analysis" title=" cepstral analysis"> cepstral analysis</a> </p> <a href="https://publications.waset.org/abstracts/183493/developed-text-independent-speaker-verification-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183493.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">58</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2117</span> The Effect of the Hemispheres of the Brain and the Tone of Voice on Persuasion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rica%20Jell%20de%20Laza">Rica Jell de Laza</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Alberto%20Fernandez"> Jose Alberto Fernandez</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Marie%20Mendoza"> Andrea Marie Mendoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Qristin%20Jeuel%20Regalado"> Qristin Jeuel Regalado</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates whether participants experience different levels of persuasion depending on the hemisphere of the brain and the tone of voice.

The temperature and heat transfer characteristics of the 200 W class woofer speaker unit were experimentally tested with the several input voice signals such as 1500 Hz, 2500 Hz, and 5000 Hz respectively. From the experiments, it can be observed that the temperature of the woofer speaker unit including the voice-coil part increases with a decrease in input voice signals. Also, the temperature difference in measured points of the voice coil is increased with decrease of the input voice signals. In addition, the heat transfer characteristics of the woofer speaker in case of the input voice signal of 1500 Hz is 40% higher than that of the woofer speaker in case of the input voice signal of 5000 Hz at the measuring time of 200 seconds. It can be concluded from the experiments that initially the temperature of the voice signal increases rapidly with time, after a certain period of time it increases exponentially. Also during this time dependent temperature change, it can be observed that high voice signal is stable than low voice signal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title="heat transfer">heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=voice%20coil" title=" voice coil"> voice coil</a>, <a href="https://publications.waset.org/abstracts/search?q=woofer%20speaker" title=" woofer speaker"> woofer speaker</a> </p> <a href="https://publications.waset.org/abstracts/5142/experimental-study-on-the-heat-transfer-characteristics-of-the-200w-class-woofer-speaker" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5142.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">360</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2114</span> The Functions of the Student Voice and Student-Centred Teaching Practices in Classroom-Based Music Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sofia%20Douklia">Sofia Douklia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present context paper aims to present the important role of ‘student voice’ and the music teacher in the classroom, which contributes to more student-centered music education.

The primary aim is to identify and consider the theoretical relevance of conceptual thought on ‘children’s voices’ for research and practice in child protection contexts. Attending to the ‘voice of the child’ has become a core principle of social work practice in contemporary child protection contexts. Discourses of voice permeate the legislative, policy and practice frameworks of child protection practices within the UK and internationally. Voice is positioned within a ‘child-centred’ moral imperative to ‘hear the voices’ of children and take their preferences and perspectives into account. This practice is now considered to be central to working in a child-centered way. The genesis of this call to voice is revealed through sociological analysis of twentieth-century child welfare reform as rooted inter alia in intersecting political, social and cultural discourses which have situated children and childhood as cites of state intervention as enshrined in the 1989 United Nations Convention on the Rights of the Child ratified by the UK government in 1991 and more specifically Article 12 of the convention. From a policy and practice perspective, the professional ‘capturing’ of children’s voices has come to saturate child protection practice. This has incited a stream of directives, resources, advisory publications and ‘how-to’ guides which attempt to articulate practice methods to ‘listen’, ‘hear’ and above all – ‘capture’ the ‘voice of the child’. The idiom ‘capturing the voice of the child’ is frequently invoked within the literature to express the requirements of the child-centered practice task to be accomplished. Despite the centrality of voice, and an obsession with ‘capturing’ voices, evidence from research, inspection processes, serious case reviews, child abuse and death inquires has consistently highlighted professional neglect of ‘the voice of the child’. Notable research studies have highlighted the relative absence of the child’s voice in social work assessment practices, a troubling lack of meaningful engagement with children and the need to more thoroughly examine communicative practices in child protection contexts. As a consequence, the project of capturing ‘the voice of the child’ has intensified, and there has been an increasing focus on developing methods and professional skills to attend to voice. This has been guided by a recognition that professionals often lack the skills and training to engage with children in age-appropriate ways. We argue however that the problem with ‘capturing’ and [re]representing ‘voice’ in child protection contexts is, more fundamentally, a failure to adequately theorise the concept of ‘voice’ in the ‘voice of the child’. For the most part, ‘The voice of the child’ incorporates psychological conceptions of child development. While these concepts are useful in the context of direct work with children, they fail to consider other strands of sociological thought, which position ‘the voice of the child’ within an agentic paradigm to emphasise the active agency of the child. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=child-centered" title="child-centered">child-centered</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20protection" title=" child protection"> child protection</a>, <a href="https://publications.waset.org/abstracts/search?q=views%20of%20the%20child" title=" views of the child"> views of the child</a>, <a href="https://publications.waset.org/abstracts/search?q=voice%20of%20the%20child" title=" voice of the child"> voice of the child</a> </p> <a href="https://publications.waset.org/abstracts/86527/reconceptualising-the-voice-of-children-in-child-protection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86527.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">137</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2110</span> On Voice in English: An Awareness Raising Attempt on Passive Voice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meral%20Melek%20Unver">Meral Melek Unver</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to explore ways to help English as a Foreign Language (EFL) learners notice and revise voice in English and raise their awareness of when and how to use active and passive voice to convey meaning in their written and spoken work. Because passive voice is commonly preferred in certain genres such as academic essays and news reports, despite the current trends promoting active voice, it is essential for learners to be fully aware of the meaning, use and form of passive voice to better communicate. The participants in the study are 22 EFL learners taking a one-year intensive English course at a university, who will receive English medium education (EMI) in their departmental studies in the following academic year. Data from students’ written and oral work was collected over a four-week period and the misuse or inaccurate use of passive voice was identified. The analysis of the data proved that they failed to make sensible decisions about when and how to use passive voice partly because the differences between their mother tongue and English and because they were not aware of the fact that active and passive voice would not alternate all the time. To overcome this, a Test-Teach-Test shape lesson, as opposed to a Present-Practice-Produce shape lesson, was designed and implemented to raise their awareness of the decisions they needed to make in choosing the voice and help them notice the meaning and use of passive voice through concept checking questions. The results first suggested that awareness raising activities on the meaning and use of voice in English would be beneficial in having accurate and meaningful outcomes from students. Also, helping students notice and renotice passive voice through carefully designed activities would help them internalize the use and form of it. As a result of the study, a number of activities are suggested to revise and notice passive voice as well as a short questionnaire to help EFL teachers to self-reflect on their teaching. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=voice%20in%20English" title="voice in English">voice in English</a>, <a href="https://publications.waset.org/abstracts/search?q=test-teach-test" title=" test-teach-test"> test-teach-test</a>, <a href="https://publications.waset.org/abstracts/search?q=passive%20voice" title=" passive voice"> passive voice</a>, <a href="https://publications.waset.org/abstracts/search?q=English%20language%20teaching" title=" English language teaching "> English language teaching </a> </p> <a href="https://publications.waset.org/abstracts/71895/on-voice-in-english-an-awareness-raising-attempt-on-passive-voice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71895.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2109</span> Phone Number Spoofing Attack in VoLTE 4G</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joo-Hyung%20Oh">Joo-Hyung Oh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The number of service users of 4G VoLTE (voice over LTE) using LTE data networks is rapidly growing. VoLTE based on all-IP network enables clearer and higher-quality voice calls than 3G. It does, however, pose new challenges; a voice call through IP networks makes it vulnerable to security threats such as wiretapping and forged or falsified information. And in particular, stealing other users’ phone numbers and forging or falsifying call request messages from outgoing voice calls within VoLTE result in considerable losses that include user billing and voice phishing to acquaintances.

VoLTE based on All-IP network enables clearer and higher-quality voice calls than 3G. It does, however, pose new challenges; a voice call through IP networks makes it vulnerable to security threats such as wiretapping and forged or falsified information. Moreover, in particular, stealing other users’ phone numbers and forging or falsifying call request messages from outgoing voice calls within VoLTE result in considerable losses that include user billing and voice phishing to acquaintances. This paper focuses on the threats of caller phone number spoofing in the VoLTE and countermeasure technology as safety measures for mobile communication networks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LTE" title="LTE">LTE</a>, <a href="https://publications.waset.org/abstracts/search?q=4G" title=" 4G"> 4G</a>, <a href="https://publications.waset.org/abstracts/search?q=VoLTE" title=" VoLTE"> VoLTE</a>, <a href="https://publications.waset.org/abstracts/search?q=phone%20number%20spoofing" title=" phone number spoofing"> phone number spoofing</a> </p> <a href="https://publications.waset.org/abstracts/21718/phone-number-spoofing-attack-in-volte" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21718.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">522</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2106</span> The Effect of Voice Recognition Dictation Software on Writing Quality in Third Grade Students: An Action Research Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Timothy%20J.%20Grebec">Timothy J. Grebec</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigated whether using a voice dictation software program (i.e., Google Voice Typing) has an impact on student writing quality. The research took place in a third-grade general education classroom in a suburban school setting. Because the study involved minors, all data was encrypted and deidentified before analysis. The students completed a series of writings prior to the beginning of the intervention to determine their thoughts and skill level with writing. During the intervention phase, the students were introduced to the voice dictation software, given an opportunity to practice using it, and then assigned writing prompts to be completed using the software. The prompts written by nineteen student participants and surveys of student opinions on writing established a baseline for the study. The data showed that using the dictation software resulted in a 34% increase in the response quality (compared to the Pennsylvania State Standardized Assessment [PSSA] writing guidelines). Of particular interest was the increase in students' proficiency in demonstrating mastery of the English language and conventions and elaborating on the content. Although this type of research is relatively no, it has the potential to reshape the strategies educators have at their disposal when instructing students on written language. <p
