By &quot;sound stretching&quot;, do you you just mean increased audio speed, or something more complicated?  I&#x27;m generally stuck at about 1.7x or 1.8x because I stop being able to make out the words even though I&#x27;m not having a problem processing them.  It&#x27;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?)<p>I&#x27;ve been dying for a audio&#x2F;video playback program that would speed up faster between pauses (breaths, breaks, etc.) while slowing down to ~1.6 speed for words.  I don&#x27;t even really know what search terms to use.  Here&#x27;s my SE question:<p><a href="http:&#x2F;&#x2F;softwarerecs.stackexchange.com&#x2F;questions&#x2F;27175&#x2F;video-playback-that-smooths-speech-at-high-speeds" rel="nofollow">http:&#x2F;&#x2F;softwarerecs.stackexchange.com&#x2F;questions&#x2F;27175&#x2F;video-...</a><p>Would love more info here.
