🗣️ Open TTS Tracker
A one stop shop to track all open-access/ source TTS models as they come out. Feel free to make a PR for all those that aren't linked here.
This is aimed as a resource to increase awareness for these models and to make it easier for researchers, developers, and enthusiasts to stay informed about the latest advancements in the field.
This repo will only track open source/access codebase TTS models. More motivation for everyone to open-source! 🤗

- ALL - Supports all natural languages; may not support artificial/contructed languages
Legend
For the above TTS capability table. Open the viewer in another window or even another monitor to keep both it and the legend in view.
- Processor ⚡ - Inference done by
- CPU (CPUs = multithreaded) - All models can be run on CPU, so real-time factor should be below 2.0 to qualify for CPU tag, though some more leeway can be given if it supports audio streaming
- CUDA by NVIDIA™
- ROCm by AMD™
- Phonetic alphabet 🔤 - Phonetic transcription that allows to control pronunciation of words before inference
- Insta-clone 👥 - Zero-shot model for quick voice cloning
- Emotion control 🎭 - Able to force an emotional state of speaker
- 🎭 <# emotions> ( 😡 anger; 😃 happiness; 😭 sadness; 😯 surprise; 🤫 whispering; 😊 friendlyness )
- strict insta-clone switch 🎭👥 - cloned on sample with specific emotion; may sound different than normal speaking voice; no ability to go in-between states
- strict control through prompt 🎭📖 - prompt input parameter
- Prompting 📖 - Also a side effect of narrator based datasets and a way to affect the emotional state
- 📖 - Prompt as a separate input parameter
- 🗣📖 - The prompt itself is also spoken by TTS; ElevenLabs docs
- Streaming support 🌊 - Can playback audio while it is still being generated
- Speech control 🎚 - Ability to change the pitch, duration, etc. for the whole and/or per-phoneme of the generated speech
- Voice conversion / Speech-To-Speech 🦜 - Streaming support implies real-time S2S; S2T=>T2S does not count
- Longform synthesis 📜 - Able to synthesize whole paragraphs, as some TTS models tend to break down after a certain audio length limit
