It is very clear to me that listening at 3x works after some training. (Not surprising, since almost everyone already reads way faster than normal speech)
The proof for this is e.g. blind people. Listen to what their screen readers sound like! I bet it will be hard to know even what language it is.
I have listened, and it's amazing, but I'm not sure they are understanding more than I would if I were scanning the page for the navigation options. (I haven't heard someone listening to a long-form text for understanding.)
