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.

Quickstart

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.
