- StyleTTS 2 (June 2023), an open text-to-speech model by Yinghao Aaron Li, Nima Mesgarani et al. that models speaking style as a latent variable sampled by diffusion, needing no reference audio, and trains end to end with large speech language models such as WavLM as discriminators; native English listeners rated it above human recordings on LJSpeech and on par on VCTK, and it beat earlier public models at zero-shot speaker adaptation. Code MIT; weights require disclosing synthetic speech.
