Lisps in Adults | Frontal Lisp | Lateral Lisp | Well Said: Toronto Speech Therapy (2024)

Lisps & Adult Articulation

A lisp is a consistently mispronounced sound that is caused by a misplacement of the tongue during speech. Typically, lisps can be divided into two types: a frontal lisp and a lateral lisp. With frontal lisps, the tongue placement is too far forward creating a "th' sound where the /s/ and /z/ sound should be. For a lateral lisp, the tongue blade is too high and lax causing air to escape over the sides of the tongue creating slushy sounding /s/ and /z/ sounds.

Lisps are relatively common and prevalence rates range from 8% to 23% in the general population. We, as speech therapists, regularly work with adults, in Toronto, who were unsuccessfully treated for lisps during the school-aged years and who want to feel more confident while speaking.

If speech therapy for your lisp didn't work in the past, fret not;we can help you resolve your frontal or lateral lisp during adulthood. A lisp can be readily corrected at any age and in as quickly as three months.
