Documentation

Voice Mode

Install via: uvx voice-mode | pip install voice-mode | getvoicemode.com

Natural voice conversations for AI assistants. Voice Mode brings human-like voice interactions to Claude Code, AI code editors through the Model Context Protocol (MCP).

🖥️ Compatibility

Runs on: Linux • macOS • Windows (WSL) • NixOS | Python: 3.10+

✨ Features

🎙️ Voice conversations with Claude - ask questions and hear responses
🔄 Multiple transports - local microphone or LiveKit room-based communication
🗣️ OpenAI-compatible - works with any STT/TTS service (local or cloud)
⚡ Real-time - low-latency voice interactions with automatic transport selection
🔧 MCP Integration - seamless with Claude Desktop and other MCP clients
🎯 Silence detection - automatically stops recording when you stop speaking (no more waiting!)

🎯 Simple Requirements

All you need to get started:

🎤 Computer with microphone and speakers OR ☁️ LiveKit server (LiveKit Cloud or self-hosted)
🔑 OpenAI API Key (optional) - Voice Mode can install free, open-source transcription and text-to-speech services locally

Quick Start

📖 Using a different tool? See our Integration Guides for Cursor, VS Code, Gemini CLI, and more!

Automatic Installation (Recommended)

Install Claude Code with Voice Mode configured and ready to run on Linux, macOS, and Windows WSL:

curl -O https://getvoicemode.com/install.sh && bash install.sh

This installer will:

Install all system dependencies (Node.js, audio libraries, etc.)
Install Claude Code if not already installed
Configure Voice Mode as an MCP server
Set up your system for voice conversations

After installation, just run:

export OPENAI_API_KEY=your-openai-key
claude converse

# Or use free local services (Voice Mode will offer to install them)
claude converse

Manual Installation

For manual setup steps, see the Claude Code Integration Guide.

🎬 Demo

Watch Voice Mode in action with Claude Code:

Voice Mode with Gemini CLI

See Voice Mode working with Google's Gemini CLI (their implementation of Claude Code):

Example Usage

Once configured, try these prompts with Claude:

👨‍💻 Programming & Development

"Let's debug this error together" - Explain the issue verbally, paste code, and discuss solutions
"Walk me through this code" - Have Claude explain complex code while you ask questions
"Let's brainstorm the architecture" - Design systems through natural conversation
"Help me write tests for this function" - Describe requirements and iterate verbally

💡 General Productivity

"Let's do a daily standup" - Practice presentations or organize your thoughts
"Interview me about [topic]" - Prepare for interviews with back-and-forth Q&A
"Be my rubber duck" - Explain problems out loud to find solutions

🎯 Voice Control Features

"Read this error message" (Claude speaks, then waits for your response)
"Just give me a quick summary" (Claude speaks without waiting)
Use converse("message", wait_for_response=False) for one-way announcements

The converse function makes voice interactions natural - it automatically waits for your response by default, creating a real conversation flow.

Configuration

📖 Integration Guides - Step-by-step setup for each tool
🔧 Configuration Reference - All environment variables
📁 Config Examples - Ready-to-use configuration files

Quick Setup

The only required configuration is your OpenAI API key:

export OPENAI_API_KEY="your-key"

Optional Settings

export STT_BASE_URL="http://127.0.0.1:2022/v1"  # Local Whisper
export TTS_BASE_URL="http://127.0.0.1:8880/v1"  # Local TTS
export TTS_VOICE="alloy"                        # Voice selection

# Or use voice preference files (see Configuration docs)\n\n# Project: /your-project/voices.txt or /your-project/.voicemode/voices.txt\n\n# User: ~/voices.txt or ~/.voicemode/voices.txt

# LiveKit (for room-based communication)\n\n# See docs/livekit/ for setup guide
export LIVEKIT_URL="wss://your-app.livekit.cloud"
export LIVEKIT_API_KEY="your-api-key"
export LIVEKIT_API_SECRET="your-api-secret"

# Debug mode
export VOICEMODE_DEBUG="true"

# Save all audio (TTS output and STT input)
export VOICEMODE_SAVE_AUDIO="true"

# Audio format configuration (default: pcm)
export VOICEMODE_AUDIO_FORMAT="pcm"         # Options: pcm, mp3, wav, flac, aac, opus
export VOICEMODE_TTS_AUDIO_FORMAT="pcm"     # Override for TTS only (default: pcm)
export VOICEMODE_STT_AUDIO_FORMAT="mp3"     # Override for STT upload

# Format-specific quality settings
export VOICEMODE_OPUS_BITRATE="32000"       # Opus bitrate (default: 32kbps)
export VOICEMODE_MP3_BITRATE="64k"          # MP3 bitrate (default: 64k)

Audio Format Configuration

Voice Mode uses PCM audio format by default for TTS streaming for optimal real-time performance:

PCM (default for TTS): Zero latency, best streaming performance, uncompressed
MP3: Wide compatibility, good compression for uploads
WAV: Uncompressed, good for local processing
FLAC: Lossless compression, good for archival
AAC: Good compression, Apple ecosystem
Opus: Small files but NOT recommended for streaming (quality issues)

The audio format is automatically validated against provider capabilities and will fallback to a supported format if needed.

Local STT/TTS Services

For privacy-focused or offline usage, Voice Mode supports local speech services:

Whisper.cpp - Local speech-to-text with OpenAI-compatible API
Kokoro - Local text-to-speech with multiple voice options

These services provide the same API interface as OpenAI, allowing seamless switching between cloud and local processing.

OpenAI API Compatibility Benefits

By strictly adhering to OpenAI's API standard, Voice Mode enables powerful deployment flexibility:

🔀 Transparent Routing: Users can implement their own API proxies or gateways outside of Voice Mode to route requests to different providers based on custom logic (cost, latency, availability, etc.)
🎯 Model Selection: Deploy routing layers that select optimal models per request without modifying Voice Mode configuration
💰 Cost Optimization: Build intelligent routers that balance between expensive cloud APIs and free local models
🔧 No Lock-in: Switch providers by simply changing the BASE_URL - no code changes required

Example: Simply set OPENAI_BASE_URL to point to your custom router:

export OPENAI_BASE_URL="https://router.example.com/v1"
export OPENAI_API_KEY="your-key"\n\n# Voice Mode now uses your router for all OpenAI API calls

The OpenAI SDK handles this automatically - no Voice Mode configuration needed!

Troubleshooting# Common Issues

No microphone access: Check system permissions for terminal/application
WSL2 Users: See WSL2 Microphone Access Guide
UV not found: Install with curl -LsSf https://astral.sh/uv/install.sh | sh
OpenAI API error: Verify your OPENAI_API_KEY is set correctly
No audio output: Check system audio settings and available devices

Debug Mode

Enable detailed logging and audio file saving:

export VOICEMODE_DEBUG=true

Debug audio files are saved to: ~/voicemode_recordings/

Audio Diagnostics

Run the diagnostic script to check your audio setup:

python scripts/diagnose-wsl-audio.py

This will check for required packages, audio services, and provide specific recommendations.

Audio Saving

To save all audio files (both TTS output and STT input):

export VOICEMODE_SAVE_AUDIO=true

Audio files are saved to: ~/voicemode_audio/ with timestamps in the filename.
