Implement voice command listener on Android phone (Termux) for hands-free SaltyBot control.

Requirements:

  • Capture audio from phone microphone via termux-microphone-record
  • Wake word detection ("Hey Salty" or configurable)
  • Stream audio to Whisper (local or Jetson) for STT
  • Parse commands: go forward/back/left/right, stop, follow me, go home, look at me
  • Publish recognized commands to /saltybot/voice/cmd via ROS2 or WebSocket
  • Audio feedback via phone speaker (TTS confirmation)
  • Graceful fallback if mic unavailable

Deliverables:

  • phone/voice_commander.py
  • Command grammar definition
  • README with setup instructions
  • Integration with teleop and navigation
