Adds phone/voice_cmd.py — a Termux-native voice command interface for SaltyBot.

What

  • Uses termux-speech-to-text (Android built-in STT) for voice recognition
  • Parses 10 command types: go forward/back, turn left/right, stop, e-stop, go to waypoint, speed up/down, status
  • Publishes structured JSON to saltybot/phone/voice_cmd via MQTT
  • TTS confirmation via termux-tts-speak after each command
  • --text flag enables manual text fallback when STT unavailable
  • paho-mqtt with auto-reconnect (same pattern as sensor_dashboard.py)

JSON payload

{"ts": 1710000000.0, "cmd": "go_forward", "param": null, "raw": "go forward", "source": "stt"}

Usage

python3 phone/voice_cmd.py --broker 192.168.1.100
python3 phone/voice_cmd.py --text   # manual fallback

Closes #633
