In this episode, Thomas Domville introduces us to the new “per voice settings” introduced with iOS 17.

These can be found by navigating to Settings > Accessibility > VoiceOver > Speech, and then selecting the language and desired TTS voice. After selecting the voice, flick up or down with one finger, or press space with dot 3 or dot 6 on a Braille display, to access the per voice settings.

The configurable parameters available vary by voice. For example, Vocalizer voices can tweak sentence pause and timbre, while for Alex you can adjust pitch range and words per minute.
