Questions

Bluetooth headsets take a moment to switch their mic on. Speechy waits for real audio before the start chime and shows “Getting mic ready…” if it takes a while.

Speechy restarts the input by itself if no audio arrives, and only stops with a message if it still hears nothing after 10 seconds.
