sudo apt-get install python3-pyaudio

A minimal Python project that recognizes basic voice commands like start, stop, pause, resume, exit, and help using your microphone and the Google Speech Recognition API. The code is under 100 lines!

• Listens for your voice through the microphone
• Recognizes and responds to these commands:
  • start: Start the system
  • stop: Stop the system
  • pause: Pause the system
  • resume: Resume from pause
  • exit/quit: Exit the program
  • help: Show available commands
• Shows the current status (Running, Paused, Stopped)
• Gives feedback in the terminal for each command

On macOS:

brew install portaudio

Create and activate a virtual environment (recommended):

python3 -m venv ../.venv
source ../.venv/bin/activate

Install Python packages:

pip install SpeechRecognition PyAudio

From the #1318_Speech_Command_Recognizer directory, simply run:

./run.sh

Or, if you want to run directly:

../.venv/bin/python Speech_Command_Recognizer.py

• Speak one of the supported commands into your microphone
• The program will print what you said and execute the command
• To stop the program, say exit or press Ctrl+C
