I've just recently experienced where VO has stopped speaking but is still running. This is when I've been in the music app, so has anyone else experienced this? When it happens, none of the gestures work either, and no sounds or haptics, too. I've had to turn off VO and turn it back on again, but in the most recent issue of this problem, it didn't help. I had to close the music app, and while a song was running, push the sleep/wake button, pick up my phone to get VO to speak, and go back into the music app just from the lock screen. Then, VO works fine ... as it used to. Keep in mind that my iPhone's one of the older models, 8+ with home button. Could this be the cause? I've not used all of the 64 gb up yet/try not to use it for more than I need, that is.
