Students speech recognition may get disabled if they cannot setup their microphone or if they experience to many problems during their lesson. To re-enable their speech follow these steps. PLEASE NOTE: You can only enable the student to turn on speech recognition. The student themselves must actually re-enable the speech recognition part of Rosetta.
After the student re-enables their speech you must disable their abilty to change their settings. If you do not they will have the abilty to change their difficulty level.
