Pausing Carousel or Variable time per slide?

Some slides are much more interesting and users want to pause on those.
I’ve found you can pause a carousel slideshow if its run on a desktop, just by hovering your mouse over it. But is there any way to do that on a mobile device? I don’t see any way.

Alternatively, if there was a way to have variable number of seconds for different slides that would also address the problem. Is there way to do this?
