How to pronounce the S and Z sounds

The voiceless (unvoiced)Ssound(IPAsymbol: s)can be found in English words such as said, sad, sit, box, bus, cats, face, and circle.

The voiced Zsound(IPAsymbol: z)can be found in English words such as zip, exist, buzz, boys, his, was, and is.

Bothof these sounds are produced in the front part of your mouth.When you make these sounds, your lips will be slightly open. Your teethshould lightly touch in the front or be very close together. The frontof your tongue will touch the back of your lower teeth. The back ofyour tongue touches the roofof your mouth on the sides.

When making the S and Zsounds,air is pushed down the center of yourtongue and betweenthe tip of your tongue and your top teeth. The movement of the airmakes the S and Z sounds.

The S sound is a hissingsound like a snake.

The Z sound is like thesound of buzzing bees.

In this video, Rachel from Rachel's English will show you how to position your mouth to makeeach of these sounds.

Voiced and voiceless sounds

In the English language, we use many voiced sounds.That meansthat the vocal cordsvibrate when you say that sound. The Z sound is a voicedsound because the vocal cords vibrate when you make the sound.

The S soundis a voiceless or unvoiced sound because the vocalcords do not vibrate when you make the sound. Instead, weuse air to make the sound.

Spellings

Thereare five common spellings of the S sound: s/ss, ce, ci, sc, and x.

Thereare three common spellings of the Z sound: z/zz, s, x.Let's look at a few rules for some of the common spellings.

• s spelling (sit,wise, dogs, cats)

  The s spelling is sometimes pronounced as an S sound (sit, cats) andsometimes as a Z sound (wise, dogs)

  It is more likely to be pronounced as a Z sound if it comesbetween two vowel sounds: wise,visit, busy.

  Thereare not many rules to help us know which sound is used, so it is veryimportant to learn the correct pronunciation of each new word.
