Revisit visual design during audio playback

[ehamner]

From observation (week 3):

It is not clear to one boy that the audio just recorded is playing back for him to hear. The classroom is loud so it is hard to hear. Also he did not really speak clearly during the recording - more like he and I talked near the kindle. This makes it hard to hear as well. When the play back screen appears he asks me "What does it say?" When the voice asks "are you ready to move on?" he can hear that clearly.

Can we visually indicate that the audio is playing back?
