We are developing a braille display keyboard for iPhone and iPad, during development, we found that there is a "delay" between the letter voices out and shows on screen. Let say I'm typing "a" (Dot 1), iOS voices out "a" immediately but then shows it on screen after a few seconds.
Is there any setting in iOS that can change/cancel this "delay" time? If not, do you think this delay is significant for most of the blind people during their typing?
Thanks and regards,
