About the S Sound

Background information to help you support your child's speech development.

The /S/ sound is a voiceless alveolar fricative and one of the most frequently occurring sounds in English. It is produced by directing a narrow stream of air over the tongue and through a small gap between the tongue tip and the ridge behind the upper teeth. Errors with this sound are commonly referred to as a lisp.

Most children master the /S/ sound by age 5-7. A frontal lisp (tongue between the teeth) is common in children under age 4-5 and often resolves naturally. A lateral lisp (air escaping over the sides of the tongue) typically requires speech therapy intervention.

How to Practice S Words at Home

Evidence-based strategies for getting the most out of word list practice.

1

Start with just 5 words at a time. Short, focused practice sessions (5-10 minutes) are more effective than long ones.

2

Say each word slowly and clearly so your child can hear the /S/ sound. Exaggerate the sound slightly.

3

Practice words in all three positions (initial, medial, final) but focus on whichever position your child finds easiest first.

4

Once individual words are easy, combine them into short phrases and sentences for carryover practice.

5

Use a mirror during practice so your child can see their mouth movements and compare them to yours.

6

Keep it fun — turn the word list into a game, use stickers as rewards, or practice during everyday activities.

How do you make the S sound?
Place the tip of your tongue just behind your upper front teeth, close to but not touching the bumpy ridge (alveolar ridge). Keep your teeth close together and your lips slightly spread. Blow a thin stream of air over your tongue tip and through the small gap between your tongue and the ridge. Your voice should be off — it is a quiet, hissing sound like a snake.
What are common S sound errors?
The most common /S/ errors are: Frontal lisp: tongue pushes between the teeth, making /S/ sound like /TH/; Lateral lisp: air escapes over the sides of the tongue, producing a slushy sound; Substituting /TH/ for /S/ (e.g., "thun" for "sun"); Omitting /S/ in blends (e.g., "top" for "stop"); Distorting /S/ so it sounds whistly or slushy.
