Voicing

A

Introducing voicing
1 Listen to the words “hiss” and “buzz.” This is the sound a snake makes: hiss hissss

This is the sound a bee makes: buzz buzzzz

2 Press your fingers against the opening of your ears, and say the word “hiss,” continuing the final s sound until you hear it clearly.

3 Press your fingers against the opening of your ears and say the word “buzz,”continuing the final z sound until you hear the difference from the s sound. The buzzing of the z sound is called voicing. z is a voiced sound. s is a voiceless sound. Note: When you whisper, you are not voicing any sounds. 4 Practice saying each sound, switching back and forth until you can hear the difference between the voiced and voiceless sounds.
