Isn't that option to slow down / speed up one of the
participant's voice also an accessibility benefit?

I can understand spanish, but not at the speed rate of a Madrileños 
speaking. Slowing down his voice would help me better understand him.
On the contrary Swiss are told to speak a slow french. I may accelerate 
this Genevois guy ;-)

More seriously, I know blind people who listen text to speech at a very 
surprising speed. But this may be a bit difficult to deal with this slow 
down / speed up option during a teleconference and stay in scynch.
