Bug description

When using VoiceOver, users do not receive status information for messages they have sent. This includes:

• Whether a message has been read or not
• Whether a voice message has been played or not
• The length of a voice message in minutes and seconds, instead of just seconds (this matches the format displayed on the screen)

Steps to reproduce

• Enable VoiceOver.
• Send a text message.
• Send a voice message.
• Move VoiceOver focus to the sent message(s) and listen to what the tts is saying.

Actual result: Text messages are read by the tts, but with no status information; for voice messages the amount of seconds (e.g. 128) is spoken, instead of minutes and seconds (e.g. 2:08).

Expected result: Status information (read/unread; length in m:ss should be included)
