Look at this video. It gives a glimpse of what voice control in iOS and iPadOS can do. I think it is incredibly impressive.
Imagine what a difference this can make for people with disabilities. Instead of tapping, tapping & holding, and swiping, you just tell your iPhone in plain language what you want it to do. I'm sure it takes some getting used to, but what doesn't?
This feature came with iOS and iPadOS 13. Go to Settings > Accessibility > Voice Control to activate it.
