Articulation & Lisps

Our articulation therapy for adults treats lisps or other concerns around pronunciation. For accents, see here. For enunciation, see here.

A lisp is a consistently mispronounced sound that is caused by a misplacement of the tongue during speech. Lisps can be divided into two types: frontal lisp and 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 placement is too far back 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 regularly work with adults 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.
