A lisp occurs when the tongue is not quite in the right place for clear articulation of certain sounds. The tongue may be protruding between the teeth, or air may be escaping along the edge of the tongue. A lisp is common, and will depend upon severity and motivation of a client as to how much therapy input is required.

What is a Lisp?

A lisp is an articulatory difficulty which can range from mild to severe. Speech and language therapy intervention will depend upon the motivation of the individual and the severity of the lisp. At Manchester SLT our speech and language therapists have various techniques and methods for clients to use to manage the effect of their lisp on their speech.

What different types of Lisp are there?

There are two different types of lisp and these are:


A frontal lisp occurs when the tongue is protruding between the teeth more than necessary for a particular sound. Most commonly the sounds which are affected with a frontal lisp are /s/ and /z/ which makes them sound like.


A lateral lisp occurs when air escapes along the sides of the tongue which makes certain phonemes sound wet as the saliva is heard.

What causes a lisp?

A lisp is habitual, therefore is caused by producing speech with an incorrect articulation pattern that has been learnt. It is possible to teach an individual, various techniques to make them aware of the sounds they produce, after this, speech and language therapy can be put in place to re-train individuals with the correct placement of the tongue for speech production. A lisp may also be caused by cleft lip and palates as well as dental problems. In these cases, speech and language therapy can be extremely beneficial and will start at an early age to ensure early intervention.
