iPhone speech rate, app problem

Good afternoon. I am using a Bluetooth keyboard with my iPhone and for some reason the speech rate keeps changing. I then have to go to settings and adjust the speech. is it possible to adjust the rate in five percent increments, or just by ten? I have the my AT&T app. Who would I need to contact concerning the inaccessibility of the app with VoiceOver with the updated version of the app? Thank you.

#1 I won't address your at&t

I won't address your at&t problem in this thread as it's a bit off topic from the subject. Turn the roter to speech rate and flick your finger up and down the screen and it should adjust. You can also adjust it from the bt keyboard wiht I believe control option cmd left and right arrow to cycle between the rotor choices then vo cmd up and down arrow to go the choices. Hth.
