Is this is only in the beginning, when you have to pronounce some of the words? I miss it :)
When you started learning any of the languages here they sometimes wanted from you to pronounce the word (which was great and embarrassing in the same time) but really great for practicing your speaking and learning. So is this option available in the long run?
Yes, it is always like that at least you turn off the option of voice exercises, it will appear always. If you have some problem to pronunce a word sometime you can mimic the records in forvo to learn how to pronunce correctly a word :D Greetings, I hope I solve your doubt.
If you turned off the microphone once in an exercise (I think the button is called "I can't use my microphone right now"), it seems to get stuck deactivated (it used to only deactivate it for an hour). You should reactivate it in your settings, as others have suggested.
