Unlearning a lisp: S exercises for children

A lisp is what you hear when S sounds “wet”, drifts toward TH, or lets air escape along the sides of the tongue. Parents then search for “lisp exercises” or “practise the S sound”: what may you do at home, and when is a speech therapist needed?

This is not a diagnosis. An S that still hisses at preschool age is often still maturation. LogiLand is practice software, not a substitute for a speech therapist and not a patient record.

Around age five, S is a typical focus; see speech therapy exercises 5 year old. Other sounds: learning to say R, pronouncing L, practicing the SCH sound and learning to say F.

Why Is S So Hard?

S is a sharp noise: teeth close together, tongue narrow, air exactly through the middle. Tiny differences are immediately audible. If the teeth open too far, or the tongue sits between the teeth, it sounds like “th” (interdental).

If air escapes along the sides, S sounds “slushy” or lateral. That last pattern is less likely to fade on its own and more often needs professional guidance (Baker & McLeod, 2011).

Children finish S later than P or M. Around 4 to 5 an imprecise S is common; persisting into school age is a reason to have someone listen, not a reason to panic on its own (McLeod & Crowe, 2018).

What makes practice harder: S sits in many words (soup, ice, school) and in clusters (stop, spoon). Every improvement is audible, and so is every comment. Tension and “put your mouth like this” often make the sound stiffer.

Parent implemented practice works in short, playful repetition in real words, not as tongue gym for homework (Heidlage et al., 2020; Wren et al., 2018). You model “sssoup”; you do not inspect teeth.

6 S Exercises at Home

Keep it short. Stop if the child starts pushing the tongue or feels watched.

1. Snake: air through a narrow gap

What are you practising? Isolated /s/, listening for sharp noise in the middle

How to do it A snake together: “ssss”. Teeth close, a smile is fine, air in the middle, no wet “th”. Then words: soup, sock, ice, bus. Isolated S first, then the word.

When? Three to five minutes, when the child is willing

Tip for parents: Do not point at the teeth like an inspector. Model “sssoup” and continue the story.

2. Soup or thoup: hear where the air is

What are you practising? The difference between a sharp S and a “th” like S

How to do it You say “soup” (sharp) and then deliberately “thoup”. “Which one sounded like a snake?” Alternate. The child points or says “snake”. No lecture on tongue place; the ear learns the difference (Preston & Edwards, 2010).

When? In the car, while dressing

Tip for parents: If you cannot hear the difference clearly yourself, skip this game. A speech therapist can train that.

3. S at the end: ice, bus, house

What are you practising? S at the end of the word, often a gentler entry

How to do it Pictures: ice, bus, house, mouse, glass. Repeat in a sentence: “The mouse eats ice.” Final S is easier for some children than “soup”, because the mouth is already “ready” (Baker & McLeod, 2011).

When? Shopping, lunch, a short book

Tip for parents: Child says “ice” without a clear S. You: “Yes, the ice is in the glass.” Expansion, no red pen (Suttora et al., 2021).

4. From T to S: a slide

What are you practising? From a sound that is already there (/t/) into noise

How to do it “t… ssss” as one slide: the tongue releases and air flows. Then “t soup” as a joke, then back to ordinary “soup”. This is a listening and play trick, not a therapy protocol. If it does not work, drop it.

When? Briefly, only if the child finds it funny

Tip for parents: This is optional. With a lateral (slushy) S, do not “push” it yourself; that is work for the speech therapist.

5. S hunt and Sam the snake

What are you practising? S words in context, then in a mini story

How to do it Find five S things: sock, juice, soap, glass, bus. Then three sentences about Sam the snake who eats soup. One sentence each turn. You put S words in without quizzing.

When? Tidy up, bedtime

Tip for parents: Follow interest. “Scooter” beats a list you invented (Dunst et al., 2016).

6. Mirror: looking, not pushing

What are you practising? Seeing that the teeth are close, without an anatomy lesson

How to do it Together at the mirror during tooth brushing. “Look, small gap, ssss.” No finger in the mouth, no “tongue behind the teeth” as an order if you are not practising that under guidance. Put it away at any discomfort.

When? One minute after brushing

Tip for parents: The mirror is optional. Many children practise better without it.

When Do You Involve a Speech Therapist?

A lisp sometimes fades, sometimes not. Talk to someone when:

• Around 5 to 6, S still sits strongly between the teeth and is not growing with the child
• S sounds lateral or “wet” and classmates comment
• Clusters (stop, school, first) hurt intelligibility
• The child avoids S, goes quiet, or is teased
• Practice creates tension or tongue pushing
• There are questions about hearing or open mouth posture
• Several sounds lag, for example also R or L

A speech therapist distinguishes a ripening S from a stuck pattern. LogiLand is not treatment. Early, targeted help is more effective than years of “it will grow out” if the child is suffering (Wren et al., 2018; Singleton, 2018).

Practical Tips

• One focus: a week of S words in play, not S and R and letters at once
• No YouTube tongue gym as a protocol: with S, the wrong tension is a risk
• Words beat isolated ssss: soup means something; ten snakes in a row get dull
• School: ask what the teacher hears
• Age five as a frame: exercises for 5 year olds place S next to R and listening games

Close

Unlearning a lisp is not a contest for the perfect snake. You practise S in soup, ice and stories, ear first. With a slushy S, teasing or going quiet: speech therapist.

General: speech therapy exercises at home.

Frequently Asked Questions

Does a lisp go away on its own? Sometimes yes, sometimes no. If S stays between the teeth and the child is commented on, screening is wise.

Is a lateral S the same as a “th” lisp? No. Air along the sides sounds different and more often needs professional help. Do not diagnose it yourself; have someone listen.

May I push the tongue into place? Preferably not. Model the sound. Pushing creates tension and belongs in treatment, not home play.

Does LogiLand replace a speech therapist? No. It is practice software. If you are worried, make an appointment.

How often should we practise? Two minutes of play every day beats one long session.
