• pygetwindow - For window management

🛠️ Troubleshooting

Common Issues:

1. PyAudio Installation Error on Windows:

# Download the appropriate wheel file from:
# https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio
# Then install with:
pip install PyAudio-0.2.11-cp39-cp39-win_amd64.whl

2. Microphone Not Working:

• Check Windows microphone permissions
• Ensure microphone is not muted
• Test microphone in other applications

3. Speech Recognition Errors:

• Check internet connection
• Speak clearly and loudly
• Reduce background noise

4. "Command not recognized":

• Speak slowly and clearly

🔒 Security Notes

• Shutdown/Restart commands require voice confirmation to prevent accidental execution
• The program only responds to recognized voice commands
• No remote access or network listening capabilities

📝 Usage Tips

1. Speak clearly and at a moderate pace
2. Wait for the "Listening..." prompt before speaking
3. Use exact command phrases for best recognition
4. Check console output for command confirmations
5. Say "help" if you forget available commands

🎛️ Customization

You can modify the voice commands by editing the process_command() method in voice_controller.py:

def process_command(self, command):
    # Add your custom commands here

        pass
