Kokoro Rust

Kokoro is a trending top 2 TTS model on huggingface. This repo provides insanely fast Kokoro infer in Rust, you can now have your built TTS engine powered by Kokoro and infer fast by only a command of koko.

kokoros is a rust crate that provides easy to use TTS ability. One can directly call koko in terminal to synthesize audio.

kokoros uses a relative small model 87M params, while results in extremly good quality voices results.

Languge support:

• English;
• Chinese (partly);
• Japanese (partly);
• German (partly);

🔥🔥🔥🔥🔥🔥🔥🔥🔥 Kokoros Rust version just got a lot attention now. If you also interested in insanely fast inference, embeded build, wasm support etc, please star this repo! We are keep updating it.

Currently help wanted! Implement OpenAI compatible API in Rust, anyone interested? Send me PR!

First, fetch the voices.json data, this is need same as Kokoro official step.

python scripts/fetch_voices.py

# test
cargo run

For production:

./target/release/koko -h
./target/release/koko -t 'Hello, this is a TTS test'

For further development, for example, supports on embeded etc, please raise an issue to discuss your requirement.
