I still haven't looked at the code, but one thing I've noticed is that the broadcast pauses as soon as the device gets locked, so maybe it would be nice to keep the screen on while you're recording?

Also, a question: how long does it take the voice broadcast to start playing? I tried listening to it ~5s after it had started and nothing came out of the speakers, I thought it was broken. Then I tried again like 20s later and it was working.

Besides that it seems to be working fine 👍 . I'll take a look at the code and approve if I don't find any major issues.

LGTM! Just the couple of questions/points mentioned above, but they're not blockers.

Keeping the screen on while recording or listening would be nice for UX if it can be implemented quickly.

@jmartinesp Thanks for your quick review! In this PR, the duration of the voice messages is 30 sec. There is no indicator in the UI about the availability of the messages, I agree it is not nice from a UX point of view.
I add the recording improvement to my todo list 👍🏻
