Quick Start

Prerequisites

• Python 3.8+

• macOS, Windows, or Linux

• Working microphone

• Claude Desktop app

Installation

1. Clone the repository:

git clone https://github.com/JWitcoff/Claude_Chat.git
cd Claude_Chat

2. Create virtual environment:

python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

3. Install dependencies:

pip install -r requirements.txt

4. Test your microphone:

python tests/test_microphone.py

5. Configure Claude Desktop (Sprint 2+): Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "voice-commands": {
      "command": "python",
      "args": ["-m", "mcp_server.voice_server"],
      "cwd": "/path/to/Claude_Chat",
      "env": {
        "PYTHONPATH": "/path/to/Claude_Chat"
      }
    }
  }
}

6. Restart Claude Desktop

Usage

Basic Commands

Say to Claude Code:

• "Activate voice mode" - Start continuous listening

• "Stop voice mode" - Stop listening

• "Hey Claude, [command]" - Wake word activation

Example Interactions

You: "Activate voice mode"
Claude: ✅ Voice mode activated

You: "Create a Python function to sort a list"
Claude: [Creates the function]

You: "Now add error handling to it"
Claude: [Modifies the code]

You: "Stop voice mode"
Claude: ✅ Voice mode deactivated

Configuration

Create a .env file:

# Recognition Settings
VOICE_BACKEND=google        # Primary: google, whisper, openai
VOICE_ENERGY_THRESHOLD=4000 # Microphone sensitivity
WAKE_WORDS=hey claude,claude

# Optional API Keys (for premium features)
OPENAI_API_KEY=sk-...       # For ultra-low latency

Development

See ROADMAP.md for the development plan and CLAUDE.md for Claude Code guidance.

Current Status

• Sprint 0: Project Setup ✅

• Sprint 1: Basic Voice Capture (In Progress)

Troubleshooting

Microphone Issues

# List available microphones
python -c "import speech_recognition as sr; print(sr.Microphone.list_microphone_names())"

# Calibrate for ambient noise
python tests/calibrate_mic.py

Recognition Issues

• Speak clearly and at normal pace

• Reduce background noise

• Adjust VOICE_ENERGY_THRESHOLD in .env
