When 'S' Quietly Turns Into a 'Z'

In Italian, the letter S tends to keep a fairly consistent, often voiceless sound. In English, though, an S between two vowels — or at the end of many plural and possessive words — very often turns into a full Z sound instead, even though it's still spelled with an S. Say 'please,' 'rose,' or 'houses' the way they're spelled, with a crisp S, and it can sound stiff or slightly off to an American ear, because native speakers expect that buzzy Z quality in these spots. Try this two-minute check: put your fingers lightly on your throat and say 'peace' versus 'please' — you should feel vibration kick in during the S in 'please' but not in 'peace.' Do the same with 'rice' versus 'rose,' and 'bus' versus 'houses.' Once you can feel the buzz turning on and off, practice saying each Z-sounding word slowly, holding that vibration steady. This tiny adjustment makes plurals, possessives, and everyday words like 'please' and 'is' sound much more natural.
