• Abstract summary: We propose an end-to-end method that is able to generate high-quality speech and better similarity for both seen and unseen speakers. The method consists of three separately trained components: a speaker encoder based on the state-of-the-art TDNN-based ECAPA-TDNN, a FastSpeech2 based synthesizer, and a HiFi-GAN vocoder.

• Abstract: In recent years, the neural network-based model for multi-speaker text-to-speech synthesis (TTS) has made significant progress. However, the current speaker encoder models used in these methods cannot capture enough speaker information. In this paper, we propose an end-to-end method that is able to generate high-quality speech and better similarity for both seen and unseen speakers by introducing a more powerful speaker encoder. The method consists of three separately trained components: a speaker encoder based on the state-of-the-art TDNN-based ECAPA-TDNN derived from speaker verification task, a FastSpeech2 based synthesizer, and a HiFi-GAN vocoder. By comparing different speaker encoder models, our proposed method can achieve better naturalness and similarity in seen and unseen test sets. To efficiently evaluate our synthesized speech, we are the first to adopt deep-learning-based automatic MOS evaluation methods to assess our results, and these methods show great potential in automatic speech quality assessment.

  Grad-StyleSpeech is an any-speaker adaptive TTS framework based on a diffusion model. It can generate highly natural speech with extremely high similarity to target speakers' voice, given a few seconds of reference speech. It significantly outperforms speaker-adaptive TTS baselines on English benchmarks.

  We introduce Wav2Seq, the first self-supervised approach to pre-train both parts of encoder-decoder models for speech data. We induce a pseudo language as a compact discrete representation, and formulate a self-supervised pseudo speech recognition task. This process stands on its own, or can be applied as low-cost second-stage pre-training.

  This paper presents a streaming speaker-attributed automatic speech recognition (SA-ASR) model that can recognize "who spoke what" Our model is based on token-level serialized output training (t-SOT) which was recently proposed to transcribe multi-talker speech in a streaming fashion. The proposed model achieves substantially better accuracy than a prior streaming model and shows comparable or sometimes even superior results to the state-of-the-art offline SA-ASR model.

We modify the acoustic model to predict joint state posteriors for all speakers, enabling the network to express uncertainty about the attribution of parts of the speech signal to the speakers.
