{"url":"/dataset/biwi-3d-audiovisual-corpus-of-affective","name":"Biwi 3D Audiovisual Corpus of Affective Communication - B3D(AC)^2","full_name":"BIWI 3D","description_markdown":"**BIWI 3D** corpus comprises a total of 1109 sentences uttered by 14 native English speakers (6 males and 8 females). A real time 3D scanner and a professional microphone were used to capture the facial movements and the speech of the speakers. The dense dynamic face scans were acquired at 25 frames per second and the RMS error in the 3D reconstruction is about 0.5 mm. In order to ease automatic speech segmentation, we carried out the recordings in a anechoic room, with walls covered by sound wave-absorbing materials.\r\n\r\nEach sentence was recorded twice:\r\n\r\n- First, the speaker read the sentence from text, with a neutral expression.\r\n\r\n- Then, the speaker watched a clip extracted from a feature film where the sentence is acted by professional actors and the context is highly emotional. After rating the emotions induced by the video, the speaker repeated the sentence.","description_withheld":null,"homepage":"https://data.vision.ee.ethz.ch/cvl/datasets/b3dac2.en.html","introduced_date":null,"introduced_date_note":null,"introduced_by":null,"license":null,"modalities":[{"name":"Texts","url":"/datasets/modality/texts"},{"name":"Audio","url":"/datasets/modality/audio"},{"name":"3d meshes","url":"/datasets/modality/3d-meshes"}],"tasks":[{"name":"3D Face Animation","url":"/task/3d-face-animation","datasets_with_task":"/datasets/task/3d-face-animation"}],"languages":[{"name":"Chinese","url":"/datasets/language/chinese"}],"variants":["Biwi 3D Audiovisual Corpus of Affective Communication - B3D(AC)^2"],"data_loaders":[],"num_papers_in_archive":5,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/3d-face-animation-on-biwi-3d-audiovisual","task":"3D Face Animation","dataset_variant":"Biwi 3D Audiovisual Corpus of Affective Communication - B3D(AC)^2","rows":5,"metrics":["Lip Vertex Error","FDD"],"first_row_in_archive_order":{"model":"SelfTalk","paper":"/paper/selftalk-a-self-supervised-commutative","metrics":{"FDD":"3.5761","Lip Vertex Error":"4.2485"},"code_links":[{"title":"psyai-net/SelfTalk_release","url":"https://github.com/psyai-net/SelfTalk_release"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/facediffuser-speech-driven-3d-facial","title":"FaceDiffuser: Speech-Driven 3D Facial Animation Synthesis Using Diffusion","date":"2023-09-20","rows_on_this_dataset":1,"code_links":1,"syntology":null},{"paper":"/paper/selftalk-a-self-supervised-commutative","title":"SelfTalk: A Self-Supervised Commutative Training Diagram to Comprehend 3D Talking Faces","date":"2023-06-19","rows_on_this_dataset":1,"code_links":1,"syntology":{"read_at":"2026-09-25T09:33:49+00:00","samples_harvested":3,"samples_ran":3,"samples_unverified":0,"pointer_only_for_licence":3,"claim":"Per-sample execution on synthesized fixtures; not a correctness claim."}},{"paper":"/paper/facexhubert-text-less-speech-driven-e-x","title":"FaceXHuBERT: Text-less Speech-driven E(X)pressive 3D Facial Animation Synthesis Using Self-Supervised Speech Representation Learning","date":"2023-03-09","rows_on_this_dataset":1,"code_links":1,"syntology":null},{"paper":"/paper/codetalker-speech-driven-3d-facial-animation","title":"CodeTalker: Speech-Driven 3D Facial Animation with Discrete Motion Prior","date":"2023-01-06","rows_on_this_dataset":1,"code_links":1,"syntology":{"read_at":"2026-09-25T09:33:49+00:00","samples_harvested":13,"samples_ran":2,"samples_unverified":11,"pointer_only_for_licence":0,"claim":"Per-sample execution on synthesized fixtures; not a correctness claim."}},{"paper":"/paper/faceformer-speech-driven-3d-facial-animation","title":"FaceFormer: Speech-Driven 3D Facial Animation with Transformers","date":"2021-12-10","rows_on_this_dataset":1,"code_links":1,"syntology":{"read_at":"2026-09-25T09:33:49+00:00","samples_harvested":4,"samples_ran":4,"samples_unverified":0,"pointer_only_for_licence":0,"claim":"Per-sample execution on synthesized fixtures; not a correctness claim."}}],"syntology_totals":{"read_at":"2026-09-25T09:33:49+00:00","papers_with_samples":3,"samples_harvested":20,"samples_ran":9,"samples_unverified":11,"pointer_only_for_licence":3,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
