Ever since I updated to one UI 3.1 I noticed that when I ask Google a question the audible voice is REALLY slow. I couldn't figure out how to speed it up. I think I figured it out today. I listen to google play books at a slightly faster play speed than default. I always have. Today for some reason the text to speech rate was playing super slow like my google assistant voice. I couldn't seem to speed it back up. BUT for some reason when I SLOWED the text to speech rate down, it sped the playback speed up! So I turned my text to speech rate down to as low as it would go, and it made the text to speech playback super fast. It's hilarious to me now. But it was really frustrating when it first started. So in summary, the faster I set the "text to speech" rate, the google play back voice becomes slower. And vice versa. I hope this gets fixed soon. And I hope this helps others who have noticed the same thing.
