Is that the challenge ID in the filename? Not sure I love it, but I don't really have any better ideas.

How come those first two don't have the same naming convention? 67fe9b-SP1.mp3 and 67fe9b-SP2.mp3

Going to approve so you can merge if you want @DanielRosa74.

Yeah, about the naming, discussing this with Huyen, this was the least complicated choice we could think of. The two different ones are the demo ones we already had in the regular path. When Huyen's PR to main is merged and platform updates, then we can remove these files. This is just to avoid not having the necessary files in the meantime.

Regarding names and whatnot: I highly recommend just giving them unique ids. There's nothing to be gained by tying them to challenge ids since you can easily search for the challenge if you know the speaking id.

but how do you know what audio file is for what challenge? If we were to just give these random ID's, we would have to listen to the audio to figure out what challenge it's for?
