By "sound stretching", do you you just mean increased audio speed, or something more complicated? I'm generally stuck at about 1.7x or 1.8x because I stop being able to make out the words even though I'm not having a problem processing them. It's hard for me to imagine 2.7x being remotely intelligible. (Can you do this for any sort of speech, or only speech where you can fill in half the words mentally?)
I've been dying for a audio/video playback program that would speed up faster between pauses (breaths, breaks, etc.) while slowing down to ~1.6 speed for words. I don't even really know what search terms to use. Here's my SE question:
