For me its simply convenience and atteniton: - audio so I can still change trains or do the dishes. Mostly pocket + ivona text to speech on my phone (takes a little effort to find an apk, the app was kinda unpublished at some point). - a bit more than double the speed to match my reading/thinking speed. Otherwise I tend to drift of in thoughts and have to rewind. If I hear a lecture and play a computer game I stick to normal speed.
