Loud Beeping Sound- Unbearable Error

There seems to be an error with this app. I just downloaded it and was completely startled when it let out incredible loud beeping sound- like a smoke alarm. It seems to have an error with the audio because it makes the sound when it should be speaking a phrase for the lesson.

This is a serious bug that needs to be fixed or else its pretty much unusable!!
