Open Voice Control preferences

Opens into the Display and Text Size section of Accessibility settings and lets you customize features like Bold Text, Larger Text, Button Shapes, On or Off Labels, Reduce Transparency, Increase Contract, Differentiate Without Color, Prefer Horizontal Text, Smart Invert, Classic Invert, Color Filters, Reduce White Point, and Auto-Brightness.

Opens the deep link into Settings for Accessibility and Siri, including controls for Type to Siri, Siri Pause Time, Speaking Rate, Spoken Responses, whether to Always Listen for “Hey Siri,” whether to Show Apps Behind Siri, whether to Announce Notifications on Speaker, and Call Hang Up with Siri during phone and FaceTime calls.

Opens the Sound Recognition section of Accessibility settings and lets you toggle the feature on or off, see how much storage is used, and choose which sounds to recognize.

Switches the Voice Control so you can issue commands to your device, giving you hands-free control of your devices.

Works great for Accessibility purposes, as well as simply using a device when you can’t reach it – I use this on my iPad Pro when it’s on the stand I have on my desk.

Opens the deep link into the Accessibility settings for Switch Control, which allows you to use your iPhone by sequentially highlighting items on the screen that can be activated through an adaptive accesssory. Other options include settings for Switches, Recipe, Scanning Style, Auto Scanning Time, Pause on First Item, Loops, Move Repeat, Long Press, Tap Behavior, Focused Item After Tap, and keyboard, switch stabilization, point scanning, audio, and menu items controls.

Opens the deep link into Settings > Accessibility > RTT to let you adjust “Real-time Text,” described by Apple as “a service offering more reliability, better text support, and the ability to speak and hear during a call” with Software and Hardware options.
