 Moonshine Voice

Voice Interfaces for Everyone

Moonshine Voice is an open source AI toolkit for developers building real-time voice agents and applications.

Full guides, models, and API reference are at moonshine-voice.readthedocs.io.

- Everything runs on-device — fast, private, and with no account or API keys.
- Optimized for live streaming, with low latency by doing work while the user is still talking.
- Speech to text models trained from scratch, from higher accuracy than Whisper Large V3 down to tiny 1MB models.
- One library across Python, JavaScript/WASM, iOS, Android, macOS, Linux, Windows, and Raspberry Pi.
- Speech to text in English, Spanish, German, Mandarin, Japanese, Korean, Vietnamese, Tagalog, Ukrainian, and Arabic, and text to speech in English, Spanish, Arabic, German, French, Hindi, Italian, Japanese, Korean, Dutch, Portuguese, Russian, Turkish, Ukrainian, Vietnamese, and Mandarin.

 Quickstart


bash
pip install moonshine-voice
moonshine-voice mic --language en


Every other platform is covered in the Quickstart, with runnable samples in Examples.

Building with a coding agent? Copy .agents/skills/moonshine-voice/ into your project's .agents/skills/ folder, or run npx skills add moonshine-ai/moonshine --skill moonshine-voice. The skill teaches the current API shape so the agent does not reach for Whisper or the old DialogFlow names.

 Documentation

- Quickstart to install and run on your platform.
- Using the Library for transcription, text to speech, and conversational agents.
- Models for what's available, accuracy, and domain customization.
