I haven't seen this mentioned anywhere, so I thought a small post was in order.
Since the latest version of watchOS; you can change speaking rate easily by pressing the crown to get to Home Screen and just flick up or down with one finger to change the rate; that is the screen that shows all the aps. I ran into this one by mistake when doing something on the watch and I did something and it slowed down. If it could slow down, then there had to be a way to speed it up again and it was soon found. It is good that this is doable without the phone having to be used.
So, is this old news?
