This PR adds a voice command interface to CompUse, allowing users to control their computer using voice commands in addition to text input.

Features Added

• Push-to-Talk Mode: Optional push-to-talk mode with customizable hotkey (Ctrl+Space)
• Audio Feedback: Text-to-speech responses when commands are recognized
• Voice Command CLI: Extended CLI interface with voice command support
• Configuration Options: Command-line options to customize voice recognition behavior

Implementation Details

• Added voice_tools.py with voice recognition and processing classes
• Created voice_cli.py that extends the existing CLI with voice capabilities
• Updated requirements.txt to include necessary dependencies
• Updated README.md with voice command documentation

How to Use

Run the voice-enabled CLI:

python voice_cli.py

With custom options:

python voice_cli.py --wake-word "assistant" --push-to-talk --verbose
