I use VoiceOver with my iPhone 6 all the time.
Sometimes, however, I hand my phone to a sighted person and turn off VoiceOver so that they can use it.
For some reason I have not been able to figure out, when a sighted person enters text into an edit field using the on-screen keyboard, the phone speaks back each word as it is entered. This occurs even when VoiceOver is turned off.
I've written to Apple Accessibility to ask what setting might be responsible but they didn't know and told me to speak to a support specialist.
Anyway, I was wondering if anyone on this list knew why this might be happening and what setting is responsible for this. There doesn't seem to be any reason the phone should be speaking with voiceOver turned off and I can't find a setting which might control this.
BTW, this has been happening even prior to iOS 11 on my iPhone 6.
thanks for any ideas.
