audio ajax

I am about to start a big project developing quizzes for a client that includes audio components for learning another language. Quiz-takers would click on an audio-linked image which would play the audio. They should be able to click on the image and listen to the audio several times, and then choose the correct answer.

Also the client wants to have some questions be an opportunity for users to record their own small audio snippets and submit them for later evaluation, like long answer questions get evaluated.
