what other people are saying. Humans often use information from our other senses, especially vision, to help us communicate (as pointed out by Harry McGurk and John MacDonald in their 1976 study “<a href="https://en.wikipedia.org/wiki/McGurk_effect" target="_blank" data-lnfb-mode="ie">Hearing Lips and Seeing Voices</a>”). For example, if you&#039;re speaking to a friend at a loud concert, you will likely focus on their face to supplement what you can hear. </p><p class="_8w6f _8w61 _8w6h"> AI researchers have recently built systems (such as Meta AI’s publicly available <a href="https://ai.facebook.com/blog/ai-that-understands-speech-by-looking-as-well-as-hearing/" target="_blank">AV-HuBERT</a> and <a href="https://arxiv.org/abs/2212.06246" target="_blank" data-lnfb-mode="ie">RAVen</a> models) that use visual information to improve performance for English speech recognition tasks. Now, Meta AI is releasing <a href="https://arxiv.org/abs/2303.00628" target="_blank" data-lnfb-mode="ie">MuAViC (Multilingual Audio-Visual Corpus),</a> the first benchmark that makes it possible to use audio-visual learning for highly accurate speech translation.

We’re excited to see how others in the research community use MuAViC to create translation systems that work well in real-world conditions. </p><h2 class="_8w6a _8w6c _8w61">Creating MuAViC</h2><p class="_8w6f _8w61 _8w6h"> Because of the scarcity of suitable training data, extending audio-visual understanding to speech translation was previously unexplored. Collecting and processing audio-video data typically requires more resources than collecting audio data alone. </p><p class="_8w6f _8w61 _8w6h"><a href="https://arxiv.org/abs/2303.00628" target="_blank" data-lnfb-mode="ie">MuAViC</a> is the first benchmark for audio-video speech translation and the largest multilingual benchmark for audio-video speech recognition. It contains roughly 1,200 hours of transcribed data spanning 9 languages. </p><p class="_8w6f _8w61 _8w6h"> For English talks, we reuse audio-visual data from the LRS3 dataset and align it with a machine translation corpus using a text-matching algorithm. Matched examples are then paired with the corresponding target sentences in the machine translation corpus for translation labels. We apply exact text matching for development set and test set examples to ensure the best accuracy. For training set examples without a match, we acquire pseudo-translation labels from a machine translation model. </p><p class="_8w6f _8w61 _8w6h"> For non-English talks, we reuse the audio-only data, transcriptions, and text translations collected in the speech translation dataset. To add the visual modality, we acquire video tracks of the original recordings and align processed video data with the audio data to create audio-visual data. Although all the audio data is transcribed, only a subset of it is translated. We acquire pseudo-translation labels using the same machine translation model as earlier. </p><h2 class="_8w6a _8w6c _8w61">Training end-to-end models</h2><p class="_8w6f _8w61 _8w6h"> We used Meta’s AV-HuBERT architecture to create end-to-end audio-video speech recognition and audio-video speech translation models. Given an aligned pair of audio-video data, our model is able to process both modalities and fuse their representations into a unified space that can be used for either speech recognition or translation tasks. And if either modality is missing, AV-HuBERT can still process the available input modality (but with less efficiency). </p><p class="_8w6f _8w61 _8w6h"><div class="_8zkc" id="u_0_i_yc"><div class="_1c_u _8zkd" id="u_0_j_7+"><div class="_53j5 _37u6 _9kkd" style="padding-bottom:56.25%;" tabindex="0" id="u_0_k_dD"><video muted="1" height="360" width="640" preload="metadata" style="" class="_ox1 _21y0" data-video-width="640" data-video-height="360" id="u_0_l_3T"></video><div class="_4ubd _170l _27db _3htz" id="u_0_m_z9"></div><div class="_m54 _1jto _3htz" id="u_0_n_J4"><img class="_1445 _2sy9 img" src="https://static.xx.fbcdn.net/rsrc.php/v3/y4/r/-PAXP-deijE.gif" alt="" style="background-image: url(&#039;https\3a //scontent-hkg1-1.xx.fbcdn.net/v/t15.5256-10/334979346_150142890948596_1342769049357495047_n.jpg?stp\3d dst-jpg_s640x640\26 _nc_cat\3d 105\26 ccb\3d 1-7\26 _nc_sid\3d d919f7\26 _nc_ohc\3d KRIYv6dQTjEQ7kNvgHR0erL\26 _nc_zt\3d 23\26 _nc_ht\3d scontent-hkg1-1.xx\26 _nc_gid\3d Ayv7xMdTrLE4ezT5UBaReqb\26 oh\3d 00_AYBRoFml-KfxlzQ8Xz9EqTVlYJZfqNA4Ahff3o2FNO2wFg\26 oe\3d 6747F638&#039;);" id="u_0_o_eX" /></div><div class="_18xu _9omd _3htz"><div class="_5l7x _360f _167h hidden_elem" id="u_0_3_ad"></div><input aria-label="&#x64ad;&#x653e;&#x5f71;&#x7247;" class="_530-" type="button" id="u_0_2_QY" /></div><div class="_4ctp _1jto _3htz"><div class="_4ctq"><div class="_4ctr" id="u_0_p_92">發生錯誤</div><div id="u_0_q_Yb">播放此影片時發生問題。若要觀看影片,請升級網頁瀏覽器。</div><div class="_5hdy"><a class="_4cts" href="/unsupportedbrowser" id="u_0_r_kP">了解詳情</a></div></div></div></div><div class="_2i84"><div id="u_0_s_ve"></div></div></div></div></p><div class="_7dik _7f2d"><div class="_7dil _9whr"></div><p class="_8w6f _8w6g"><div>In this video, the model must deal with background music (rather than background noise, as in the first video above).</div></p></div><p class="_8w6f _8w61 _8w6h"> Our model’s most noteworthy feature is its robustness to noise.
