"Tongue twisters are phrases or sentences which are hard to speak fast, usually because of alliteration or a sequence of words with very similar sounds. Tongue twisters help develop speech skills in young children as well as older children who need additional help with speech therapy.\n"^^<http://www.w3.org/2001/XMLSchema#string>
