Keeping this in consideration, can you cure a lisp?
For these people, speech pathologists can help with therapy (or “training” if the term is preferred), ideally based on principles of motor speech. But only for people who want help to get rid of their lisp. If you have a lisp and want help, we've developed a course for you.
Beside above, can a lisp be corrected in adults? Lisps are common and can be corrected through speech therapy. It is important to treat the patient early, however, adults can also benefit from therapy if they have a lisp.
Also question is, can a child outgrow a lisp?
In most cases, a lisp is not developmental in nature, but rather a deviation in tongue placement at rest or during speech (and swallowing). What that means is that the majority of children who are lisping when they start to speak do not grow out of it. This is not an absolute rule.
Are lisps normal?
It is a perfectly normal developmental phase for some (not all) children to produce interdental or dentalised /s/ and /z/ sounds until they are about 4½ years of age. On the other hand, neither lateral or palatal lisps are part of the normal developmental progression.
