VoiceMode
Natural voice conversations with Claude Code (and other MCP capable agents)
VoiceMode enables natural voice conversations with Claude Code. Voice isn't about replacing typing - it's about being available when typing isn't.
Perfect for:
- Walking to your next meeting
- Cooking while debugging
- Giving your eyes a break after hours of screen time
- Holding a coffee (or a dog)
- Any moment when your hands or eyes are busy

Quick Start
Requirements: Computer with microphone and speakers
Option 1: Claude Code Plugin (Recommended)
The fastest way for Claude Code users to get started:
# Add the VoiceMode marketplace claude plugin marketplace add mbailey/voicemode # Install VoiceMode plugin claude plugin install voicemode@voicemode ## Install dependencies (CLI, Local Voice Services) /voicemode:install # Start talking! /voicemode:converse
Option 2: Python installer package
Installs dependencies and the VoiceMode Python package.
# Install UV package manager (if needed) curl -LsSf https://astral.sh/uv/install.sh | sh # Run the installer (sets up dependencies and local voice services) uvx voice-mode-install # Add to Claude Code claude mcp add --scope user voicemode -- uvx --refresh --from voice-mode voicemode-mcp-launcher # Optional: Add OpenAI API key as fallback for local services export OPENAI_API_KEY=your-openai-key # Start a conversation claude converse
For manual setup, see the Getting Started Guide.
Features
- Natural conversations - speak naturally, hear responses immediately
- Works offline - optional local voice services (Whisper STT, Kokoro TTS)
- Low latency - fast enough to feel like a real conversation
- Smart silence detection - stops recording when you stop speaking
- Privacy options - run entirely locally or use cloud services
Compatibility
Platforms: Linux, macOS, Windows (native or WSL), NixOS Python: 3.10-3.14
Configuration
VoiceMode works out of the box. For customization:
# Set OpenAI API key (if using cloud services) export OPENAI_API_KEY="your-key" # Or configure via file voicemode config edit
See the Configuration Guide for all options.
Permissions Setup (Optional)
To use VoiceMode without permission prompts, add to ~/.claude/settings.json:
{
"permissions": {
"allow": [
"mcp__voicemode__converse",
"mcp__voicemode__service"
]
}
}
See the Permissions Guide for more options.
Local Voice Services
For privacy or offline use, install local speech services:
- Whisper.cpp - Local speech-to-text
- Kokoro - Local text-to-speech with multiple voices
These provide the same API as OpenAI, so VoiceMode switches seamlessly between them.
Installation Details
System Dependencies by Platform
Ubuntu/Debian
sudo apt update sudo apt install -y ffmpeg gcc libasound2-dev libasound2-plugins libportaudio2 portaudio19-dev pulseaudio pulseaudio-utils python3-dev
WSL2 users: The pulseaudio packages above are required for microphone access.
Fedora/RHEL
sudo dnf install alsa-lib-devel ffmpeg gcc portaudio portaudio-devel python3-devel
macOS
brew install ffmpeg node portaudio
NixOS
# Use development shell nix develop github:mbailey/voicemode # Or install system-wide nix profile install github:mbailey/voicemode
Alternative Installation Methods
From source
git clone https://github.com/mbailey/voicemode.git cd voicemode uv tool install -e .
NixOS system-wide
# In /etc/nixos/configuration.nix
environment.systemPackages = [
(builtins.getFlake "github:mbailey/voicemode").packages.${pkgs.system}.default
];
Troubleshooting
| Problem | Solution |
|---|---|
| No microphone access | Check terminal/app permissions. WSL2 needs pulseaudio packages. |
| UV not found | Run curl -LsSf https://astral.sh/uv/install.sh | sh |
| OpenAI API error | Verify OPENAI_API_KEY is set correctly |
| No audio output | Check system audio settings and available devices |
