VoiceMode
An MCP server and Claude Code plugin that enables natural voice conversations with Claude Code and other MCP-capable AI agents, supporting both cloud (OpenAI) and fully local (Whisper + Kokoro) speech processing with smart silence detection.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Voice/audio MCP interface. Audio data may contain sensitive speech. TTS/STT provider credentials must be secured. Voice biometrics should not be stored without consent.
⚡ Reliability
Best When
You want to talk to Claude Code naturally during development without touching the keyboard, with the option to keep everything fully local for privacy.
Avoid When
You need low-latency, high-accuracy voice for production use cases — dedicated voice platforms like Deepgram or AssemblyAI are better suited.
Use Cases
- • Hands-free AI coding assistance while walking, cooking, or away from keyboard
- • Voice-driven development sessions during extended screen-time breaks
- • Privacy-first local voice interaction using on-device Whisper and Kokoro models
- • Accessible AI interface for users who prefer or require speech input
Not For
- • Production voice applications or customer-facing voice bots
- • High-volume or multi-user voice processing
- • Voice interaction with non-MCP AI systems
Interface
Authentication
Optional OpenAI API key for cloud STT/TTS. No auth required for fully local mode using Whisper + Kokoro.
Pricing
MIT licensed. Local-only mode is completely free with no external dependencies beyond system audio libraries.

Known Gotchas
- ⚠ Requires FFmpeg, portaudio, and platform-specific audio libraries installed on host
- ⚠ Local Whisper model download needed on first use (~hundreds of MB)
- ⚠ Silence detection may cut off speech prematurely in noisy environments
- ⚠ WSL on Windows requires additional audio routing configuration
