I’ve partially implemented what you asked for, in that you can now re-play audio with an on-screen button and with a keyboard shortcut, as described here: Play voice more than 1 - #3 by Steve
I understand that you want to hear the audio before clicking the token. Sorry to disappoint you but this is a larger change since it would require putting audio buttons next to all options, or maybe playing them all in sequence, or letting you tap first with an extra CHECK button press to confirm (like Duolingo does), or just playing the audio for the correct answer but then that gives the game away completely invalidating the challenge. All of these come with compromises so I’m not going to do this at the moment.
