You might wonder if you can correct a lisp on your own. But the answer to this question isn’t a straightforward one. There are many factors that influence a person’s speech, and speech therapists are uniquely trained to identify and treat articulation disorders like a lisp. If you try to fix a lisp without the guidance of a speech therapist, it can actually become worse.
Key takeaways
A person with a lisp has difficulty pronouncing the /s/ and /z/ sounds due to incorrect tongue positioning and movement.
A lisp can be corrected in both children and adults. With speech therapy, many people see a major improvement in their ability to speak clearly.
The best way to fix a lisp is by working with a licensed speech therapist. In lisp speech therapy, you will learn the tongue placement needed to say the /s/ sound correctly, at various levels of speech.
It may be tempting to try fixing a lisp on your own, but it’s important to work with a speech therapist to avoid worsening the lisp or causing new speech problems.

Get startedWhat causes a lisp?
A lisp is an incorrect production of the /s/ and /z/ sounds. A lisp is caused by an incorrect motor pattern of tongue positioning and movement.
When a person has a lisp, they’re positioning their tongue in a way that blocks the airflow needed to make the /s/ and /z/ sounds. That distorted airflow creates the lisping sound.
Appropriate articulation is important because it helps people communicate clearly. Plus, /s/ and /z/ are sounds that occur often in the English language. Lisps can make people feel self-conscious and cause challenges in their social and professional lives.
Can a lisp be corrected?
Here’s the good news–a lisp can be corrected at any age, even as an adult! With the right speech therapy, many people see a major improvement in their ability to speak clearly. A speech therapist will evaluate and determine:
If a lisp is present and if so, what type of lisp it is
The possible causes or underlying factors, such as a tongue thrust, hearing loss, or structural changes in the mouth
Your personal goals for your speech
With this information, a speech therapist can create an individualized treatment plan to help you overcome speech challenges, identify and fix sounds you’re producing incorrectly, and achieve your goals. They should also give you customized activities you can practice at home between sessions to boost your progress.

What is the best way to get rid of a lisp?
The best way to “fix” a lisp is by working with a licensed speech therapist. In lisp speech therapy, you will learn to say the /s/ sound correctly at various levels, in a specific order, so you can achieve success.
You may start by saying the sound on its own, then work your way up to saying it in words and then sentences. As you show readiness, the speech therapist will guide you to practice at more complex levels, using their clinical judgment to help you make the quickest progress.
Learning how the mouth moves to make sounds is a foundational skill needed to accurately produce speech sounds.
Learning how the mouth moves to make sounds is a foundational skill needed to accurately produce speech sounds. Your speech therapist will likely teach correct tongue placement first, both in resting position and for speech. Normal resting posture for the tongue looks like this:
The tongue is slightly suctioned to the roof of the mouth, with the tip of the tongue resting on the alveolar ridge (not on the back of the teeth).
The jaw should be relaxed, and the lips should be closed.
Breathing should happen through the nose.
You will also learn how to position your tongue muscles to produce a clear /s/ and /z/ sound. Your speech therapist will have a variety of techniques they use to teach this.
To make the /s/ sound, the tongue tip should barely touch the bumpy part behind the top front teeth. The sides of the tongue should be raised enough to touch the insides of the top back molars. The air is directed only out of the front of the mouth. The voice is off, meaning the vocal cords do not vibrate, resulting in a quiet sound.
Speech therapy practice will be repetitive to help you learn the correct “motor pattern” for accurately saying the /s/ and /z/ sounds.

Can you train yourself out of a lisp?
A big part of successful speech therapy is practicing at home, between sessions. But it’s important that you practice in the right way, under the guidance of a speech therapist. Practicing a sound incorrectly, at a higher level than you’re ready for, can cause you to form an incorrect motor pattern. You would then need to “unlearn” that motor pattern in order to say the sound correctly.
It’s important to practice correctly to avoid worsening the lisp or causing new problems.
It may seem tempting to try fixing a lisp on your own, especially with so many resources and videos available online. But it’s important to practice correctly to avoid worsening the lisp or causing new problems. Having a speech therapist monitoring this process is your best bet!
When to see a speech therapist for a lisp
Most adults are conscious of their speech and how they communicate. However, the impact of speech on a person’s social life and career is unique to that person. Lisping is not necessarily a negative! In fact, some adults celebrate their lisp.

Frequently asked questions (FAQs)
Adults may have a lisp for several reasons, including incorrect tongue placement learned in childhood, a history of tongue thrust, a tongue tie, or jaw alignment differences. Some adults simply never received treatment as children. If a lisp is affecting your clarity or confidence, consider contacting a speech therapist for an evaluation to explore your options.
People can outgrow a lisp. However, if a lisp persists in a child past 5 years old, speech therapy may be needed to correct it.
Some mild interdental lisps can improve with focused practice and visual feedback, like watching tongue placement in a mirror or trying the “exploding /t/” technique. However, many people need speech therapy in order to change long-standing speech habits.
Coverage depends on your insurance plan and whether the lisp is considered medically necessary. For children, especially when a lisp affects speech clarity or development, coverage is more common. For adults seeking treatment mainly for cosmetic or confidence reasons, some plans may not cover it. It's best to call your insurer directly or speak with a speech therapy provider who can help verify your benefits.
