A Comparative Study on Speaker-attributed Automatic Speech Recognition in Multi-party Meetings

no code implementations31 Mar 2022 Fan Yu, Zhihao Du, Shiliang Zhang, Yuxiao Lin, Lei Xie

Therefore, we propose the second approach, WD-SOT, to address alignment errors by introducing a word-level diarization model, which can get rid of such timestamp alignment dependency.

Speaker Embedding-aware Neural Diarization: an Efficient Framework for Overlapping Speech Diarization in Meeting Scenarios

1 code implementation18 Mar 2022 Zhihao Du, Shiliang Zhang, Siqi Zheng, Zhijie Yan

Through this formulation, we propose the speaker embedding-aware neural diarization (SEND) framework, where a speech encoder, a speaker encoder, two similarity scorers, and a post-processing network are jointly optimized to predict the encoded labels according to the similarities between speech features and speaker embeddings.
