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 plugin marketplace
claude plugin marketplace add mbailey/plugins

# Install VoiceMode plugin
claude plugin install voicemode@mbailey

## 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 voice-mode

# 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 (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.

Remote Agent (Operator)

VoiceMode includes agent management for running headless Claude Code instances that can be woken remotely from the iOS app or web interface.

Quick Start

# Start the operator agent in a tmux session
voicemode agent start

# Check if it's running
voicemode agent status

# Send a message to the operator
voicemode agent send "Hello, please check my calendar"

# Stop the operator
voicemode agent stop

The Operator Concept

The operator is a headless Claude Code instance running in tmux that:

• Listens for remote connections from voicemode.dev
• Can be woken by the iOS app or web interface
• Responds via voice using VoiceMode's TTS/STT capabilities

Think of it like a phone operator - always there to help when called.

Agent Commands

Command	Description
voicemode agent start	Start operator in tmux session
voicemode agent stop	Send Ctrl-C to stop Claude gracefully
voicemode agent stop --kill	Kill the tmux window
voicemode agent status	Show running/stopped status
voicemode agent send "msg"	Send message (auto-starts if needed)
voicemode agent send --no-start "msg"	Send message (fail if not running)

Agent Directory Structure

Agent configuration lives in ~/.voicemode/agents/:

~/.voicemode/agents/
├── voicemode.env       # Shared settings for all agents
├── AGENT.md            # AI entry point
├── CLAUDE.md           # Claude-specific instructions
├── SKILL.md            # Shared behavior
└── operator/           # Default agent
    ├── voicemode.env   # Operator-specific settings
    ├── AGENT.md
    ├── CLAUDE.md
    └── SKILL.md        # Operator behavior

Configuration (voicemode.env)

Agent-specific settings override base settings. Available options:

# Base settings (~/.voicemode/agents/voicemode.env)
VOICEMODE_VOICE=nova           # Default TTS voice
VOICEMODE_SPEED=1.0            # Speech rate

# Operator settings (~/.voicemode/agents/operator/voicemode.env)
VOICEMODE_AGENT_REMOTE=true    # Enable remote connections
VOICEMODE_AGENT_STARTUP_MESSAGE=  # Message sent on startup
VOICEMODE_AGENT_CLAUDE_ARGS=   # Extra args for Claude Code

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

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

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

Save Audio for Debugging

export VOICEMODE_SAVE_AUDIO=true
# Files saved to ~/.voicemode/audio/YYYY/MM/
