tts-web

Converts text to speech in the browser with two lightweight voice models, multilingual Pocket TTS in review.

Browser-native text-to-speech, 100% client-side via Rust/WASM. Two engines: Pocket TTS (autoregressive, Mimi codec decoder, streaming) and KittenTTS (single forward pass, StyleTTS2 distilled, 14M params). Weights on HuggingFace as GGUF/safetensors; 0.23-0.24 RTF native. Multilingual Pocket TTS (French, German, Spanish, Italian and Portuguese, next to English) is in review, and matches the official implementation frame for frame in F32.
