Have you tried tongue-twisters? A tongue-twister is a phrase that is deliberately designed to be difficult to say. Especially, at speed!  These can be a lot of fun in small groups or even when practicing them alone. Some tongue-twisters are designed to produce results that are amusing when mispronounced. Others simply rely on creating confusion when mistakes are made. The idea of the tongue twister may have originated from the art of alliteration.

For example, Black bug bit a big black bear. Over the years, tongue-twisters seem to have been offered up for everything from curing hiccoughs to testing the fit of dentures. More recently researchers into neuroscience have also used them to monitor brain functions. https://www.psychologytoday.com/gb/blog/the-athletes-way/201312/tongue-twisters-reveal-quirky-...
