Playing sound in specifik order

Hi! 

I am a language teacher and I have looked at language learning apps for mobile phones, which seem to work very well 

for students. I think one of the reasons is the very simple design and the many repetition of sound.

Would it be possible to play the audiofiles in course presentation in a specifik order ? And would it be possible 

to play an audiofile after the correct answer has been selected by the student? 

Kind Regards

Malte
