Playback rate/speed control for "Read Aloud" feature (text-to-speech, TTS)

I think the text-to-speech synthesis is very high quality and it’s a very nice addition, but a big drawback is the lack of any control over the playback speed/rate.

It’s also quite helpful being able to adjust based on the density of the content and the speed it can be absorbed. A shopping list for a 5yr old’s birthday party, and an explanation of the Weinberg–Witten theorem can be understood at different rates…
