What is a lisp?
A lisp is known to be a mispronounced sound which is caused by the misplacement of the tongue during speech. There are two types of lisp:
- Frontal lisp — This happens when the tongue is placed too far forward therefore making a /th/ sound for /s/ and /z/ sound (e.g.: saying thunk when you meant skunk)
- Lateral lisp — This happens when the tongue is placed too far back which causes air to escape from the sides of the tongue therefore making a slushy sound for /s/ and /z/ (e.g.: yeth for yes)
How to correct it?
A lisp can be readily corrected at any age and as quickly as within 3 months. However, the best way to correct it is to approach a professional. To fully understand the treatment process for lisp, it would be best if you contact a speech therapist and make an appointment to get the lisp treated.
