Triggers
- User sends an audio message.
- User says "activa modo walkie-talkie" or "hablemos por voz".
Constraints

- Maintain a fast response time (RTF < 0.5).
- Always reply with BOTH text (for clarity) and audio.
Manual Execution (Internal)
To respond with voice manually:
bin/sherpa-onnx-tts /tmp/reply.ogg "Tu mensaje aquí"
Then send /tmp/reply.ogg via message tool with filePath.
