Also question is, how do you encourage s sound?
Practicing blowing air through a straw can help elicit this. The trick is to not let the air escape from the sides of the mouth. Hold the straw on the center of their bottom lip. Have them make the /s/ sound and if they are making it correctly you will hear the air come through the straw.
One may also ask, how do you elicit an S sound SLP? To make the /z/ sound, the top of the tongue nearly touches the roof of the mouth (alveolar ridge), the little bumpy bit behind the top teeth. The lateral (side) edges of the tongue lightly touch the upper back teeth. The vocal folds vibrate which can be felt if you place a finger on your larynx during /z/ production.
In this manner, how do I teach my child the s sound?
For correct /s/ productions, the tongue tip should be elevated behind the top teeth. Have your child identify the “bumpy spot†behind their top teeth. This is where the tongue tip should be placed. As your child vocalizes the /s/ sound, the air flow should go over the top of their tongue and out the front of the mouth.
How is the S sound made?
The correct production for an “s†sound is made with the teeth nearly closed in a natural bite position and the lips parted as though smiling. The sides of the tongue are in a raised position against the upper side teeth.
