Natural voice conversations for AI assistants. Voice Mode brings human-like voice interactions to Claude, ChatGPT, and other LLMs through the Model Context Protocol (MCP).

🖥️ Compatibility

Runs on: Linux • macOS • Windows (WSL) | 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:

  1. 🔑 OpenAI API Key (or compatible service) - for speech-to-text and text-to-speech
  2. 🎤 Computer with microphone and speakers OR ☁️ LiveKit server (LiveKit Cloud or self-hosted)

Quick Start

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

npm install -g @anthropic-ai/claude-code curl -LsSf https://astral.sh/uv/install.sh | sh claude mcp add --scope user voice-mode uvx voice-mode export OPENAI_API_KEY=your-openai-key claude converse

Voice Mode with Gemini CLI

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

Voice Mode with Gemini CLI

Example Usage

Once configured, try these prompts with Claude:

  • "Let's have a voice conversation"
  • "Ask me about my day using voice"
  • "Tell me a joke" (Claude will speak and wait for your response)
  • "Say goodbye" (Claude will speak without waiting)

The new converse function makes voice interactions more natural - it automatically waits for your response by default.

Configuration

Quick Setup

The only required configuration is your OpenAI API key:

export OPENAI_API_KEY="your-key"

Optional Settings

# Custom STT/TTS services (OpenAI-compatible) 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 # LiveKit (for room-based communication) # 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" # 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
  • 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.
