How to add a voice recorder widget/interaction?

Well, that's my question. It's because I'm working now on a project that simulates the new TOEIC Speaking and Writing test, which is basically an online test, and I need to record students' answers to grade them later. BTW, I already checked this other thread Voice Recording and Playback widget which is pretty much what I'm looking for. I just opened this new discussion because it seems that's an old topic, and chances are that there might be a widget with this functionality by now. Thanks!
