Speech pathologists from Kids First Children’s Services in Sydney’s northern beaches explain why some kids lisp and what parents can do to help.
A lisp is a speech sound error that usually presents when a child (or adult!) has difficulty placing their tongue in the correct position to produce /s/ and /z/ sounds.
When your children are learning how to speak, they might lisp naturally…and up until the age of about 4 and a half, this is completely typical.
Depending on the type and severity if the lisp, most children grow out of this speech sound error, but for some kids, the problem does not resolve on its own.
This is sometimes because some children may have learned to say a particular sound the wrong way in the first place.
If this has happened to your child, the incorrect production of the /s/ and /z/ sounds may have become a habit.
After the age of 4 ½ to 5, lisping is no longer considered part of typical speech development.
If your lisping child is at, or about to start school, they should no longer be lisping and their their speech sounds should be investigated further by a speech pathologist.
Early intervention can prevent your child’s lisp from affecting their confidence and speaking clarity.
|1. Interdental Lisp|
Tongue sticks out between the front teeth, making /s/ and /z/ sound like “th” (e.g. yes à yeth or say à thay)
Part of Typical Speech
Development until about
4 ½ years of age
|2. Dentalised Lisp|
Tongue touches front teeth while producing /s/ and /z/ sounds, pushing air outwards, which produces a muffled sound
|3. Lateral Lisp|
Air escapes over the sides of the tongue, giving the impression that there is a ‘wet’, ‘slushy’ or ‘spitty’ sound because you can hear trapped saliva
Not Part of Typical
|4. Palatal Lisp|
The /s/ and /z/ sounds are made with the tongue pushed against the soft palate (the back of the roof of the mouth) producing more of a “hy” sound
When a lisp is identified, the need for speech therapy will depend on the severity of the lisp.
For some kids, lisping on its own may not significantly alter or reduce their ability to be understood by others, but it might affect their confidence or social interactions.
