StyleTTS 2
Facts from StyleTTS 2's own pages
- Code license
- The repository states that its code is licensed under the MIT License. · github.com, 13 Oct 2026
- Compute requirements
- The repository notes that training or inference can run into out-of-memory issues and recommends reducing batch size or maximum audio length; it also says older GPUs may produce background noise. · github.com, 13 Oct 2026
- Dependencies
- The repository says its inference depends on a GPL-licensed package that is not included directly, and also links to a fully MIT-licensed package using gruut with lower output quality due to a phonemizer mismatch. · github.com, 13 Oct 2026
- Evaluation
- The makers report that StyleTTS 2 surpasses human recordings on single-speaker LJSpeech and matches them on multispeaker VCTK, as judged by native English speakers. · styletts2.github.io, 12 Oct 2026
- Expressiveness
- The sample page demonstrates expressive speech, style transfer, longform narration, and speech diversity. · styletts2.github.io, 13 Oct 2026
- Inference
- The repository provides inference notebooks and pretrained model downloads for LJSpeech and LibriTTS. · github.com, 13 Oct 2026
- Installation
- The repository lists Python 3.7 or newer as a prerequisite and gives additional installation instructions for Windows. · github.com, 13 Oct 2026
- Known limitation
- The repository says the distributed-data-parallel version of second-stage training does not work, so the current version uses data parallelism. · github.com, 13 Oct 2026
- Language support
- The repository says non-English training requires a pretrained PL-BERT model for the language and points to a multilingual PL-BERT supporting 14 languages. · github.com, 13 Oct 2026
- Limitations
- The README says the second-stage training code uses data parallelism because its distributed data parallel version does not work. · github.com, 12 Oct 2026
- Linux dependency
- The demo instructions say to install phonemizer and espeak-ng; the example espeak-ng command uses apt-get. · github.com, 12 Oct 2026
- Model use
- For pretrained models, the repository asks users to disclose synthesized speech unless they have permission to use the cloned voice, and says public voice use requires speaker permission or disclosure. · github.com, 13 Oct 2026
- Online demo
- The repository links to a Hugging Face online demo. · github.com, 13 Oct 2026
- Open source license
- The repository code is licensed under the MIT License. · github.com, 12 Oct 2026
- Platforms
- windows,linux,self_hosted · styletts2.github.io, 20 Sept 2026
- Pretrained models
- The repository links pretrained models for LJSpeech and LibriTTS. · github.com, 12 Oct 2026
- Purpose
- StyleTTS 2 is a text-to-speech model that uses style diffusion and adversarial training with large speech language models. · styletts2.github.io, 13 Oct 2026
- Speaker adaptation
- The project reports that its LibriTTS-trained model outperforms previous publicly available models for zero-shot speaker adaptation. · styletts2.github.io, 13 Oct 2026
- Speech naturalness
- The model uses pre-trained speech language models such as WavLM as discriminators and differentiable duration modeling to improve speech naturalness. · styletts2.github.io, 12 Oct 2026
- Speech quality
- The authors report that it surpasses human recordings on the single-speaker LJSpeech dataset and matches them on multispeaker VCTK, as judged by native English speakers. · styletts2.github.io, 13 Oct 2026
- Style generation
- It models speaking styles as latent random variables and uses diffusion to generate a suitable style without reference speech. · styletts2.github.io, 13 Oct 2026
- Style transfer
- The model can transfer an emotional style sampled from emotional text to input text that has no emotional content. · styletts2.github.io, 12 Oct 2026
- Voice cloning
- Yes · styletts2.github.io, 20 Sept 2026
- Voice use terms
- For pretrained models, the README says users must have permission to clone a speaker's voice or publicly disclose that the generated voice is synthesized. · github.com, 12 Oct 2026
