Better Speech Language Pathologists Answer:
THERE ARE A FEW TYPES OF LISPS:
Interdental lisp: This is the most common lisp and is sometimes called a frontal lisp. In this lisp, the /s/ and /z/ sounds are made with the tongue sticking out from between the front teeth.
Dentalized lisp: The tongue pushes against the front teeth, which directs air flow forward. Some therapists suggest waiting until a child is 7 or older to correct but the longer one waits the harder it may be to fix.
Lateral lisp: Air escapes from the sides of the mouth and a person sounds slushy or spitty since air and saliva are mixing.
A palatal lisp: The tongue is positioned too far back making speech sound hollow (on the /s/ or /z/ sounds). This is not typical during speech development and a children's speech therapist should be seen to address this lisp.
WHAT CAN CAUSE A LISP?
They can be causes by improper placement of the tongue in a person's mouth which changes the way air flows and therefore the sound becomes distorted when speaking. The chances someone has a lisp can be increased by:
Tongue sucking as a child
Tongue thrust: this is a swallowing pattern in which the tongue is sticking out of the tongue during a swallow. This type of swallow pattern should be corrected by your speech language pathologist
Braces or other dental appliances
Unknown causes in which a lisp continues
HOW DO I FIX A LISP OR HELP MY CHILD WORK ON THEIR LISP?
These types of issues may be sometimes difficult to treat at home because it means breaking a physical habit that a person has been using for a long time. So the earlier a speech language pathologist can provide treatment, the better the chances are that the lisp will disappear.
Here are some suggestions from the Better Speech therapists for how to help a lisp:
Increase your child's awareness that they are lisping by identifying where proper tongue placement is.
Model the /s/ or /z/ sound and have your child watch your mouth
Tell your child that their tongue is called Sandy the Snake; Sandy should not come out of his cage (their mouth) when speaking. Try to catch Sandy!
Try to break the thumb sucking habit (not easy we know!)
If your child has an open mouth posture when breathing, have them checked for allergies. An open mouth can cause the tongue to stick out.
