Correct, I've had it show all the phone tree options as soon as the phone tree starts playing. So, yes, it will reduce time to navigate the tree in that way.
Also, it often prevents me from having to listen to the tree twice, if I am looking for a better option and then decide a previous one was actually the better fit.
