Speech Therapy Lisp

Speech Therapy to Treat Lisps

Ask a Speechie provides speech therapy for lisps. A “lisp” is a lay term to describe difficulty achieving the correct tongue position when pronouncing /s/ and /z/ sounds. The lisp may persist into adulthood if untreated, but can be successfully treated in motivated children and adults.

Waiting beyond the age of 4 ½ to treat a lisp strengthens the “habit” and is not recommended. However, the correct age to intervene may vary depending on the child’s maturity and motivation. Treatment for a lateral lisp (when the /s/ and /z/ sounds are made with the air escaping over the sides of the tongue and out the side of the mouth) is recommended for children under 4 ½ years of age.
