FEATURE: Would text to speech rendering make sense here?

[mofosyne]

Maybe after the bell, you might want text to speech to announce periods or special events or emergency procedures.

You will likely need two approaches

• Structured : Series of templated text messages with %VARIABLE% representing 'period number' or 'day' or 'event name' etc...
• Unstructured/Freeform : Straight TTS of text for full control

Being that this is a wall powered device, you don't really need to worry about energy efficiency, but you may want to render the audio ahead of time and spend extra cpu cycles to make sure the audio quality is very clear
