Interesting. Never thought of speech as different than music but I guess it really is. The frequency range, the modulation, the timing...

It would be interesting to see how many people would actually use this. After all, not many people use or need to use speech in their games. And I'm not sure this would change if it were readily available in 3DGS.

Don't know. Never thought of using speech myself. Might be worthwhile to poll the community and see not how many people would use it (cause then everyone will jump on the bandwagon) but rather how many people have THOUGHT of using speech in their game.
