Wow, sorry but this is very misinformed. A lot of people me included can listen to audio at 2x. I constantly listen to podcasts (so not a slow narration to begin with) at 2x in English which is not even my native language and I understand everything and enjoy it very much.
Blind users listen at 4x without loss of understanding.
