uvatbc,
Nice work! I use it mainly for listening to voicemails (since google transcribe-to-sms sucks..). Would it be possible to allow the user to select which speakers to play the voicemail from? For instance, I would like voicemails to play out of the speaker you use when you hold the device to your face to make a call. That way people around me cannot hear voicemails if I am not using a headset of any kind.
