No they won't because they won't have the sound files, they'll have to download them and install them on their local files.
I do like the idea, maybe at the very least have your characters voice depend on which type you choose, it'd be some effort to implement for a gimmick but it could be nice to add a little bit more immersion!
I believe the original voice actor for this was Merc_Shpongled who, if I remember correctly, has a lot of recording equipment as he does a lot of sound based stuff. Don't hold me to that but that's just off the top of my head.
I support this regardless but I think if it gets accepted, it'd be something on the back burner.
