StreamVoice is a language model-based zero-lip speech conversion model that enables real-time conversion without the need for a complete source speech. It employs a fully causal context-aware language model combined with a time-independent acoustic predictor capable of processing semantic and acoustic features alternately at each time step, thus eliminating the dependence on the complete source speech. In order to enhance the performance degradation caused by incomplete context that may occur in streaming processing, StreamVoice enhances the context awareness of the language model through two strategies: 1) teacher-guided context foresight, which uses the teacher model to summarize current and future semantic context during the training process and guides the model to predict the missing context; 2) semantic masking strategy, which promotes acoustic prediction from previously damaged semantic and acoustic input to enhance context learning capabilities. Notably, StreamVoice is the first language model-based streaming zero-lip speech conversion model without any future prediction. Experimental results show that StreamVoice has streaming conversion capabilities while maintaining zero-lip performance comparable to non-streaming voice conversion systems.

StyleTTS 2 is a text-to-speech (TTS) model that uses large-scale speech language models (SLMs) for style diffusion and adversarial training to achieve human-level TTS synthesis. It models style as a latent random variable through a diffusion model to generate a style that best fits the text without reference to speech. Furthermore, we use large pre-trained SLMs (such as WavLM) as the discriminator and combine them with our innovative differentiable duration modeling for end-to-end training, thereby improving the naturalness of speech. StyleTTS 2 outperformed human recordings on the single-speaker LJSpeech dataset and matched them on the multi-speaker VCTK dataset, gaining approval from native English-speaking reviewers. Furthermore, our model outperforms previous publicly available zero-shot extension models when trained on the LibriTTS dataset. By demonstrating the potential of style diffusion and adversarial training with large SLMs, this work enables a human-level TTS synthesis on single and multi-speaker datasets.

SALMONN is a large language model (LLM) developed by the Department of Electronic Engineering of Tsinghua University and ByteDance that supports speech, audio events and music input. Unlike models that only support speech or audio event input, SALMONN can perceive and understand a variety of audio inputs, enabling emerging capabilities such as multilingual speech recognition and translation, and audio-speech co-reasoning. This can be seen as giving LLM "hearing" and cognitive hearing capabilities, making SALMONN a step towards an artificial general intelligence with hearing capabilities.
