Earlier comments on this thread mentioned that slow down / speed up may 
be inconvenient in a live teleconference setup, but there seem to be a 
case for such a feature in other contexts (playback of spoken material, 
mostly, be it recorded or synthesised).

Would you be interested in drafting a relevant use case scenario?
