Mobile: Use headphone button to toggle mic / trigger speak #1098
Description
Feature Request
When using the SpeakMCP mobile app with headphones connected, allow the headphone button (e.g. play/pause or center button) to toggle the microphone on/off or trigger the speak action.
Use Case
Users wearing headphones should be able to activate voice input without needing to tap the screen — just press the headphone button to start/stop speaking.
Possible Implementation
- Listen for remote control / media button events (AVAudioSession remote command center on iOS, or MediaSession API on Android/web)
- Map the play/pause or center button press to toggle mic recording
- Could also support double-press or long-press for additional actions
Expected Behaviour
- Single press headphone button → toggle mic on/off (or trigger speak)
- Visual/audio feedback to confirm mic state change
