Best Ways to Get Rid of a Lisp

Sure, it was cute to watch a young Ron Howard mix up his sibilants (“S” sounds) and interdentals (“TH” sounds) as he sang about the Wells Fargo Wagon coming down the “thweet” in The Music Man, but in reality, a lisp is not usually as endearing, especially in adults. It’s a fairly obvious, stigmatizing malfunction of the mouth. In some cases the cause is physiological—related to an oral deformity or nasal condition. However, that doesn’t mean that the solution is necessarily physical. The cause is more often psychological: childhood stress or a ploy for attention. It might also just be a normal part of learning to talk for some children under five years of age.

Correcting speech impediments is itself an area of study and the focus of some folks’ entire working life. I wholeheartedly suggest that you get in contact with a speech/language pathologist for more specific, more individual advice—especially if the lisp is not resolved naturally by the time the child is five to six years of age. That being said, the methodology for correcting a lisp isn’t a complicated one. It just requires persistence in practice, accuracy in correction, and the patience to follow through and practice.

What is a Lisp?

  • Interdental lisps. These lisps happen when people put their tongues between their teeth while trying to make an “S” sound, but what comes out is more of a “TH” sound.
  • Dentalized lisps. This kind of lisp involves people putting their tongues against their front teeth when they talk. It makes them harder to understand as their pronunciation tends to be muffled.
  • Lateral lisps. When people put their tongues against the roof of their mouths while they talk, it makes everything sound sort of wet since the sound goes around the side of the tongue.
  • Palatal lisps. This also deals with people’s tongues and the roof of the mouth; only this involves the middle of the tongue and the soft part of the palate.

Best Ways to Get Rid of a Lisp

Is the tongue against the teeth or the roof of the mouth? Is the lisp sound pure “TH” or is it slushy? Are there other speech impediments apparent? Switching “R’s” and “W’s” are also quite common. When looking inside of the mouth, is the tongue obviously larger than it should be? Any missing teeth? Is the individual a mouth breather? It could be that a chronically stuffy nose is the actual cause of the lisp. If you notice any kind of physical malady that you think might be inhibiting speech development, it would be advisable to talk to a physician about it. Sometimes, though, a speech therapist will have techniques that are more effective if the lisp persists.

It might be good to start this, at least at first, in a one-on-one situation. Pick a private location free from distractions. Ask the individual to make the lisp sound. Sometimes a prolonged, teeth together, sibilant “sssss” will bring it out. When she is aware that the sound is happening, ask her to take notice of where her tongue is in her mouth. How are her teeth placed? Are her lips open or closed?

In sibilant sounds, the tongue doesn’t really need to be involved. If he is raising that tongue up against the roof of his mouth, pressing it against his upper teeth, or sticking it in between his front teeth, have him practice keeping his tongue against his bottom teeth as he says monosyllabic word that start with an “S,” such as: say, saw, see, sick, so, soup, suds, etc.

You’ve shown her that although it may sound similar, the “Th” sound, which comes from the tongue, is not the same thing. She has been practicing making “S” sounds followed by vowel sounds and succeeding. It is time to make it harder by having her go from that teeth and tongue position to another, and back again within the same word. Start with words like: success, Sundays, Irish setters, simpleness, seashells, sonorous, simplicity, succinct, etc.

He has built from the base sounds (phonemes) and proper tongue and teeth placement, up to multisyllabic words. Now it is time to start practicing the reading of those words within sentences. Pay special attention to the transition from preceding words and how he proceeds to the following word. Work on making that transition seamless. If there is a pause before a problem word, that is something to work on—have him repeat the transition between the two words over and over until it is correct.

Other Lisp Options

Teeth Smiling Method.When learning to get rid of lisps, it can be beneficial to have the individual look at herself in the mirror as she talks. As luck would have it, a big wide smile (the kind that shows some teeth) puts the mouth in the perfect position to create the sibilant “Sss” sound. Smile the way to success!

Mouth exercises. This is another fun thing for a youngster to do in front of a mirror. Have him practice moving his tongue around in his mouth as you direct him. Also, sticking his tongue out and moving it back and forth can help to strengthen his tongue. This trains him to have better control, thus overcoming the lisp.

  • Say this shortly; say this softly.
  • Say this sixteen times in succession.

  • The shells she sells are from the sea, I’m sure.

Practice, Practice, Practice

Practice is what is going to make getting rid of a lisp happen. Making this process a fun one that is goal oriented, collaborative, and self moderating will help to keep the individual on task and motivated. You will have to be the judge of what learning style will work the best for the individual in question. Some people respond well to rote memorization and repetition, but my experiences working with special needs kids has shown me that interactivity and being a good role-model can go a long way towards keeping someone engaged. Most people won’t have the technology that can be found in a lot of modern classrooms, but the same types of interactive things can be done on paper with flashcards, matching games, etc.; it’s just not as flashy.
