Hi @PatriciaValdez1,
If you mean name pronunciation, then the suggestion from @jsowalsk is a great one (and the one we use at my institution). If you mean pronunciation in general, like for a language/speech class, you could look at some of the general audio/video management systems (like Yuja, Panopto, Kaltura, or Canvas Studio). While they advertise more as video-focused, I believe most of them handle audio too, and may have some form of commenting features built in. Of course, these platforms are going to come at an additional cost, but I'm hoping this might give you a direction to look depending on your exact needs.
