StyleTTS 2 at a glance
Checked 15 Oct 2026Research code for the StyleTTS 2 paper (arXiv 2306.07691). Code is MIT; the pretrained checkpoints on Hugging Face carry no licence file, only usage terms in the README requiring you to disclose synthetic speech or have the speaker's permission. Inference runs from Jupyter notebooks and depends on a GPL-licensed phonemizer, which is why it is not bundled. English-focused (the PL-BERT module is English-only). Inference hardware is not documented. Last push to the repo was August 2024.
RepoQuarry. “StyleTTS 2.” Checked 15 Oct 2026. https://repoquarry.dev/projects/styletts2How much of ElevenLabs does it replace?
2 of 4 jobs. Research-grade English TTS with zero-shot speaker adaptation from the LibriTTS model; inference is via notebooks, not a ready app, and other languages need a different PL-BERT.
For speech recognition, voice agents, see other ElevenLabs alternatives. You may also need to build an interface, an API server and hosting yourself.
How much of Descript does it replace?
2 of 3 jobs. Voice cloning and text-to-speech only; no transcript-based audio or video editing.
For transcript-based editing, see other Descript alternatives. You may also need to build an interface, an API server and hosting yourself.

Before using these pre-trained models, you agree to inform the listeners that the speech samples are synthesized by the pre-trained models, unless you have the permission to use the voice you synthesize.github.com · StyleTTS2#inference ↗ 1d ago
However, the inference depends on a GPL-licensed package, so it is not included directly in this repository.github.com · StyleTTS2#inference ↗ 1d ago
