• Authors: Tanel Pärnamaa, Ando Saabas,
• Abstract summary: We propose to use the internal representation of the PSE model itself as the speaker embedding. We show that our approach performs equally well or better than the standard method of using a pre-trained speaker embedding model.

• Abstract: Personalized speech enhancement (PSE) models can improve the audio quality of teleconferencing systems by adapting to the characteristics of a speaker's voice. However, most existing methods require a separate speaker embedding model to extract a vector representation of the speaker from enrollment audio, which adds complexity to the training and deployment process. We propose to use the internal representation of the PSE model itself as the speaker embedding, thereby avoiding the need for a separate model. We show that our approach performs equally well or better than the standard method of using a pre-trained speaker embedding model on noise suppression and echo cancellation tasks. Moreover, our approach surpasses the ICASSP 2023 Deep Noise Suppression Challenge winner by 0.15 in Mean Opinion Score.

  We propose SelectTTS, a novel method to select the appropriate frames from the target speaker and decode using frame-level self-supervised learning (SSL) features. We show that this approach can effectively capture speaker characteristics for unseen speakers, and achieves comparable results to other multi-speaker text-to-speech frameworks in both objective and subjective metrics.

  This study addresses the problem of single-channel Automatic Speech Recognition of a target speaker within an overlap speech scenario. In the proposed method, the hidden representations in the acoustic model are modulated by speaker auxiliary information to recognize only the desired speaker. Experiments on the WSJ corpus show that the proposed speaker conditioning method is an effective solution to fuse speaker auxiliary information with acoustic features for multi-speaker speech recognition.

  optimizing speech towards a particular test-time speaker can improve performance and reduce run-time complexity. We propose using an ensemble model wherein each specialist module denoises noisy utterances from a distinct partition of training set speakers. Grouping the training set speakers into non-overlapping semantically similar groups is non-trivial and ill-defined.
