The method follows that proposed by Chen (1997), in which acoustic nasality can be measured by the difference between the amplitude of the vowel\u0026amp;#39;s first formant (A1), and the amplitude of the nasal peak amplitude in the vowel\u0026amp;#39;s first or second harmonic (P0). The measurements were taken at three different time points (start, mid, end) in the vowel. The results show that the main difference between nasal and nasalized vowels is at the vowel\u0026amp;#39;s end, the nasal vowel being considered more nasal than its nasalized counterpart. This difference may hint on perceptual clues to distinguish nasal from nasalized vowels in Brazilian Portuguese.","author":[{"@context":"https://schema.org","@type":"Person","name":"Luciana

Despite common belief that the language possesses contrastive nasal vowels, literature examination shows that nasal vowels may be followed by a nasal resonance, while nasalized vowels must be followed by a nasal consonant. It is argued that the nasal resonance may be the remains of a consonant that nasalizes the vowel, making nasal vowels simply coarticulatorily nasalized (e.g. [1]). If so, vowel nasality should not be more informative for the perception of a word containing a nasal vowel than for a word containing a nasalized vowel, as nasality is attributed to coarticulation. To test this hypothesis, randomized stimuli containing the first syllable of words with oral, nasal and nasalized vowels were presented to BP listeners who had to identify the stimuli original word. Preliminary results demonstrate that accuracy decreased for nasal and nasalized stimuli. A comparison between patterns of response to measured degrees of vowel acoustic nasality and formant values demonstrate that vowel quality differences may play a more relevant role in word identification than type of nasality in a vowel.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Perception and acoustics of vowel nasality in Brazilian Portuguese","attachmentId":62263965,"attachmentType":"pdf","work_url":"https://www.academia.edu/42129024/Perception_and_acoustics_of_vowel_nasality_in_Brazilian_Portuguese","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/42129024/Perception_and_acoustics_of_vowel_nasality_in_Brazilian_Portuguese"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="6693996" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/6693996/Nasal_Coda_and_Vowel_Nasality_in_Brazilian_Portuguese">Nasal Coda and Vowel Nasality in Brazilian Portuguese</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="10915078" href="https://usp-br.academia.edu/BeatrizRaposodeMedeiros">Beatriz Raposo de Medeiros</a></div><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Nasal Coda and Vowel Nasality in Brazilian Portuguese","attachmentId":33418138,"attachmentType":"pdf","work_url":"https://www.academia.edu/6693996/Nasal_Coda_and_Vowel_Nasality_in_Brazilian_Portuguese","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/6693996/Nasal_Coda_and_Vowel_Nasality_in_Brazilian_Portuguese"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="2" data-entity-id="22612368" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/22612368/On_the_Duration_of_Nasal_Vowels_in_Brazilian_Portuguese">On the Duration of Nasal Vowels in Brazilian Portuguese</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="8869876" href="https://ufmg.academia.edu/RuiRotheNeves">Rui Rothe-Neves</a></div><p class="ds-related-work--abstract ds2-5-body-sm">This study aims to reassess the findings of Moraes & Wetzels (1992) on the duration of distinctive nasal vowels of BP by including more vowels and contexts. According to the hypothesis, a longer duration of nasal vowel is a manifestation, at the level of phonetic implementation, of an underlying bimoraic representation which cause nasal vowels to be longer than oral vowels and also longer than allophonic nasal vowels, whose representation is monomoraic. We recorded three repetitions of 15 words representing five different contexts by subjects of the Belo Horizonte dialect. Analysis by mixed effects models showed that the hypothesis is only borne out in the behavior of [a] before plosive and [i] before fricative. The hypothesis was then recast in terms of moraic primacy: speakers show greater variation in their time of articulation in different segments when such segments are occupied by just one mora. We analyzed the variation in vowel duration for oral and nasal [a, i] when followed by plosive or fricative. Although vowels are longer before plosives than fricatives, this difference was here only attested in oral vowels. This is consistent with the hypothesis that two morae use up more phonological time, thus constraining coarticulatory variation in phonetic timing.</p><div class="ds-related-work--ctas"><button

class="ds-related-work--abstract ds2-5-body-sm">This study investigates coarticulatory effects caused by the following consonant-either a stop or a fricative-on the duration of the oral and the nasalized portion of the nasal vowel and the nasal murmur in sequences within Portuguese words like tensa [ˈtẽsɐ] 'tense' versus tenta [ˈtẽtɐ] '(s/he) tries.' The results replicate previous observations that duration adjustments affect the vowel's nasalized portion, as is the case for languages in which the speaker intends nasalization. The second hypothesis is that adjustments in duration as a function of the following onset do not affect the nasalization duration, but only the timing of a nasal gesture relatively constant in duration. Results show that irrespective of the following consonant ([s] or [t]), nasalization remains constant in duration. However, a shorter nasal murmur or a more extended postnasal consonantal oral portion does not follow more extended vowel nasalization. As the entire VNC sequence increases on an individual basis, so does the nasalization. Still, increasing nasalization comes at a cost for the duration of the oral part of the vowel irrespective of [s, t]. These results are compatible with that speaking rate influences coordination timing between the beginning of the vowel and the beginning of nasalization.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Durational aspects of tautosyllabic vowel nasalization in (Brazilian) Portuguese: An airflow investigation","attachmentId":81981913,"attachmentType":"pdf","work_url":"https://www.academia.edu/73471714/Durational_aspects_of_tautosyllabic_vowel_nasalization_in_Brazilian_Portuguese_An_airflow_investigation","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/73471714/Durational_aspects_of_tautosyllabic_vowel_nasalization_in_Brazilian_Portuguese_An_airflow_investigation"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="70835189" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/70835189/A_Nasofiberscopic_Study_of_Nasalized_Diphthongs_in_Brazilian_Portuguese">A Nasofiberscopic Study of Nasalized Diphthongs in Brazilian Portuguese</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="3764589" href="https://independent.academia.edu/RitaDemasi">Rita Demasi</a></div><p class="ds-related-work--metadata ds2-5-body-xs">2019</p><p class="ds-related-work--abstract ds2-5-body-sm">This study analyses the velum movement in Brazilian Portuguese nasalized diphthongs. The study was made with a nasofiberscope to study the size and the movements of the velopharyngeal opening during the production of monosyllabic words containing oral and nasal diphthongs [ej], [ẽȷ]̃, [aw] and [ãw̃]. The data show that the velum lowering is gradual and that different movements are observable in the velopharyngeal opening. These data confirm previous observations showing that there are several phases in Brazilian Portuguese nasalized diphthongs. The velum lowering has three different phases. The findings show that: the anticipatory velum lowering is variable, while the closing movement is stable and the presence of the nasal appendix appearing in all the nasalized segments.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"A Nasofiberscopic Study of Nasalized Diphthongs in Brazilian Portuguese","attachmentId":80416626,"attachmentType":"pdf","work_url":"https://www.academia.edu/70835189/A_Nasofiberscopic_Study_of_Nasalized_Diphthongs_in_Brazilian_Portuguese","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/70835189/A_Nasofiberscopic_Study_of_Nasalized_Diphthongs_in_Brazilian_Portuguese"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="7" data-entity-id="113986616" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/113986616/TAUTOSYLLABIC_VOWEL_NASALIZATION_IN_THE_PORTUGUESE_OF_S%C3%83O_TOM%C3%89">TAUTOSYLLABIC VOWEL NASALIZATION IN THE PORTUGUESE OF SÃO TOMÉ</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="268037827" href="https://unicamp.academia.edu/AmandaMacedoBalduino">Amanda Macedo Balduino</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Dialectologia, 2023</p><p class="ds-related-work--abstract ds2-5-body-sm">In this study, we analyze tautosyllabic vowel nasalization in Santomean Vernacular Portuguese (SVP) spoken on São Tomé Island. In European and Brazilian varieties of Portuguese, vowel nasality has been considered both a phonological (actual nasal vowels) and a phonetic (nasalized vowels) feature. Herein, we share an acoustic analysis demonstrating that nasalized vowels in SVP are 48% longer than their oral counterparts. Thus, a nasalized vowel could correspond to an underlying sequence of an oral vowel followed by a nasal consonant. In this sense, a nasal coda's nasal feature would spread to the continuous vowel on the left. After that, the nasal coda, which triggers the process, is deleted at the segmental tier without changing the syllable length. This suggests a biphonemic interpretation of vowel nasality in SVP. Accordingly, there are no phonological nasal vowels in SVP. As São Tomé and Príncipe is a multilingual country, we investigate the influences triggered or reinforced by linguistic contact between Portuguese and other languages spoken in the country, especially Santome.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button"
