Hello, my name is________________. I'm taking American Accent Training. There's a lot to learn, but I hope to make it as enjoyable as possible. I should pick up on the American intonation pattern pretty easily, although the only way to get it is to practice all of the time. I use the up and down, or peaks and valleys, intonation more than Iused to. I've been paying attention to pitch, too. It's like  walking down a staircase. I've been talking to a  lot of Americans lately, and they tell me that I'm easier to understand. Anyway, I could go on and on, but the important thing is to listen well and sound good.

The following exercise will let you hear and practice S with its dual sound. There are many more Z sounds in English than S sounds.
