Try adjusting the playback speed. Tap on the cog-looking symbol in the lower right of the video; should show a playback speed option. It probably says normal. Click/tap on it and it should give a list of numbers. I’ve found .75 seems to be the right speed for a fast talker.
The voice pitch changes some, and it might seem a bit draggy if you’re used to hearing that speaker at full speed, but not bad enough to annoy.
You, young lady, are worth your weight in gold, or whichever precious metal is fetching the most these days (and I’m sure you’ll tell me what that metal is shortly lol).
I put it on .75 and it is PERFECT. Thank you so much. Very helpful.
