White on Black
Use White on Black to invert the colors on the iPhone screen, which may make it
easier to read the screen. When White on Black is turned on, the screen looks like a
photographic negative.
Invert the screen’s colors: In Settings, choose General > Accessibility and tap the
“White on Black” switch.
Mono Audio
Mono Audio combines the sound of the left and right channels into a mono signal
played on both sides. This enables users with hearing impairment in one ear to hear
the entire sound signal with the other ear.
Turn Mono Audio on or off: In Settings, choose General > Accessibility and tap the
Mono Audio switch.
Speak Auto-text
Speak Auto-text speaks the text corrections and suggestions iPhone makes when
you’re typing.
Turn Speak Auto-text on or off: In Settings, choose General > Accessibility and tap
the Speak Auto-text switch.
Speak Auto-text also works with VoiceOver or Zoom.
