audio mode for quiz

[wptmdoorn]

audio mode for quiz, consisting of:

• text-to-speech for asking questions
• microphone input coupled to speech-to-text to answer these questions; most likely true / false and multiple choice will be easy to implement. Open questions are harder; they would likely need to reply with the correct answer and ask the user if their answer is correct

Ultimately it would be better to have a long-standing 'audio' connection between user<-> system so that the user does not have to repress the microphone each time.
