VoiceSmith MCP
Local AI voice for coding assistants. Gives your AI a real voice (text-to-speech) and ears (speech-to-text) via the Model Context Protocol (MCP). Fully offline — no cloud APIs, no data leaves your machine.
What You Get
- 54 distinct voices via Kokoro ONNX (local TTS, ~300MB model)
- Speech-to-text via faster-whisper (local STT, ~150MB model)
- Voice activity detection via Silero VAD (local, 2MB)
- Multi-session support — run multiple Claude Code sessions, each with its own voice (single session for Cursor/Codex)
- Works with Claude Code, Cursor, and Codex
Quick Start
npx voicesmith-mcp install
The installer will:
- Check system dependencies (Python 3.11+, espeak-ng, mpv)
- Set up a Python virtual environment with all packages
- Download TTS and STT models
- Configure your IDE’s MCP settings
- Let you pick a voice
- Inject voice behavior rules so the AI knows how to speak
Restart your IDE session after installing. The AI will greet you by voice on the first response.
Usage
[!NOTE] Everything works out of the box. After installing, just start a session — the AI speaks automatically. No configuration needed. The installer sets up voice behavior rules that teach the AI when and how to use its voice.
What the AI does automatically:
| Moment | What happens |
|---|---|
| You give it a task | Gets to work (speaks only when clarifying approach) |
| It finishes work | Speaks a summary of what was done |
| It has a question | Asks out loud, then listens for your voice response |
| Voice tools unavailable | Falls back to text silently |
Changing Voices Mid-Session
Ask the AI to switch voices at any time:
“Switch to Nova”
If the voice is available, the AI switches immediately. If it’s occupied by another session, the AI will tell you and show available alternatives.
Browse all 54 voices:
“Show me the available voices”
Or preview them in a terminal: npx voicesmith-mcp voices
Voice Persistence
[!TIP] When you switch voices, the choice is saved automatically. Next time you start or resume a session, the AI uses the same voice — no need to switch again.
Muting
In a meeting or shared space? Just ask:
“Mute the voice”
The AI continues working normally — it just won’t play audio. Say “unmute” when you’re ready.
