How it works
These tongue twisters with S and Z set the hiss against the buzz. There are 40, written for this site, in four groups: at the start of a word, at the end, in plural endings, and both in one word.

Same place, voice off or on
S and Z are made in one place, with the tongue at the ridge behind the top teeth. S is breath alone; for Z the vocal cords vibrate. Hold a long sss with two fingers on your throat, then change it to zzz and feel the buzz start. Then say "Sip and zip, sap and zap, sing and zing."
The plural that buzzes
A plural is spelled with s and often said with Z. After p, t, k, f and th the ending is S, as in cats and books. After other consonants and after vowels it is Z, as in dogs and bees. After a hissing sound, as in buses and dishes, it is an extra syllable that ends in Z.
Questions and answers
What are some tongue twisters with S and Z?
Try "Zoe sips soda at the zoo." or "Nice price, wise prize, twice the size." For plural endings, "Ants on plants, bees on trees, frogs on logs." For both sounds in one word, "Sausages sizzle while the citizens snooze."
Why does S sometimes sound like Z?
English spells both sounds with the letter s: is, his, has, these, please, noise and cheese all end in the Z sound. The S sound can also hide in the letter c, as in nice, price and circled.
Why is the Z sound hard for some English learners?
Many languages have no Z. The PHOIBLE database of the world's sound systems lists Z in about 3 in 10 of them and S in about two thirds, so for many learners Z is the new one of the pair.
Are there tongue twisters with only S?
Yes. The S tongue twisters page keeps to the hiss: S at the start, in blends, at the end and beside Sh. All of these lines are practice, not speech therapy; for a child's speech, ask a speech-language pathologist.
