As young children develop their speech and language skills, imperfections are to be expected. Errors are often a part of typical development, and are extremely common.
Lisps are one of the most noticeable speech disorders that can happen during this period of development. People with lisps often struggle to pronounce certain consonants, with the “s” and “z” sounds being some of the most common and challenging.
In many cases, lisps are just temporary bumps in the road on the path to language development, and over time they’re corrected naturally on their own. However, while a lisp might seem “cute” or “adorable” during a child’s toddler years, it can be concerning if the lisp persists as they get older. The number one question parents typically ask is “will my child grow out of it?” Many parents worry that their child’s lisp will continue into school-age and eventually adulthood, and potentially impact their child’s confidence and self-esteem.
Fortunately, there are effective treatments available, as well as many ways parents can reinforce good communication habits at home to prevent a lisp from becoming more pronounced.
As with all speech and language challenges, educating yourself is the best way to make informed treatment decisions. For that reason, we’ve put together this informational guide to answer common questions about lisps, identify signs and symptoms, explain how a lisp is typically evaluated, diagnosed, and treated, and more.
Many of us intuitively know what a lisp sounds like, with the most common form occurring when someone makes a “th” sound when trying to say a “s” or “z” sound. Lisps are caused because of the incorrect placement of a person’s tongue inside their mouth during speech. When a person lisps, their tongue usually touches, pushes against, or protrudes between their teeth.
There are actually four distinct types of lisps depending on certain characteristics and tongue placement. While the differences can seem nuanced, correct diagnosis is important when considering treatment.
Lisps often become noticeable after the age of two when children begin developing their language abilities.
Both dentalized and interdental lisps are common and perfectly normal during a child's language development phase. Many children experience them until around 4 ½ years of age. While it’s always a good idea to consult with a qualified speech-language pathologist if you suspect your child has a lisp (more on that below), it’s especially important once your child exceeds that age range.
Conversely, lateral and paternal lisps do not happen as part of a child’s natural development. A child with this type of lisp should receive a professional evaluation from a speech-language pathologist as soon as possible.
Yes, there is a difference between a tongue thrust and lisp. However, the distinction can be hard to identify with an untrained eye and best left to the clinical assessment of a speech-language pathologist.
A tongue thrust is technically referred to as an orofacial myofunctional disorder (OMD). It occurs when the tongue moves forward in a pronounced way when a person is either speaking or swallowing. The tongue may sit too far forward in the mouth, or push between a person’s teeth during speech and swallowing. Articulation errors can result from both tongue thrusts and lisps, affecting the production of sound.
A person’s lisp can be a result of a tongue thrust. This is especially important to know because a tongue thrust in particular can eventually cause significant dental issues if left untreated.
Lisping often doesn’t have a severe impact on a person’s intelligibility and ability to be understood. However, a lisp can still have consequential effects on a person’s social and emotional wellbeing.
Some parents fear their child could be unduly teased by their peers. Children may also feel anxious or uncomfortable when speaking in a social situation, which can affect their confidence, self-esteem, and ability to socialize with others.
For adults, these effects can be worsened. They may feel frustration or embarrassment in the workplace, and try to avoid certain social situations altogether.
While lisps affect everyone differently, there are effective interventions that parents and adults can take to minimize the impact of lisps and regain normal speech.
As mentioned, lisps are caused by the incorrect placement of the tongue in the mouth. This can in turn obstruct air flow when speaking, and cause the distortion of how an individual pronounces words and syllables. Lisps can be caused by a variety of factors including:
In most cases, your pediatrician, school nurse, or teacher may refer you to a speech-language pathologist (SLP). Speech therapists are communication experts and are the most qualified professionals to help assess, evaluate, and treat children and adults with lisps.
As mentioned, there are many types of lisps of varying severities that can impact your child’s speech. That’s why if you suspect your child has a lisp, it’s a good idea to be proactive and seek an assessment from a speech therapist. To assess your child’s speech patterns, your speech therapist may:
Habits are harder to break over time. Therefore, the earlier treatment is provided, the quicker a lisp can be corrected and your child’s overall communication will improve.
Once your speech therapist assesses your child’s speech, identifies the type of lisp they have, and recognizes which sounds they’re mispronouncing, they’ll develop a tailored treatment plan designed to help your child reach their communication goals. This plan will often include helping your child:
Every child is different, and therefore the frequency and intensity of treatment will shift depending on their needs. While some children can see considerable improvement in a month or two, others will need prolonged intervention for a year or more. Factors that can affect the length of treatment include your child’s age, type of lisp, awareness of mispronunciations and ability to self-correct, how well they follow directions, and the frequency of at-home practice.
First things first, it’s never too late to correct a lisp.
Many adults have lisps that were never properly treated in their younger years. They may express feelings of frustration, embarrassment, or low self-esteem, and want to improve their communication to feel more confident when speaking in their daily lives and workplace.
However, it’s also important to note that not all adults with a lisp have a desire to seek therapy - and that’s perfectly okay! Oftentimes, these adults have accepted their speech the way it is, and it has become part of their unique image and persona.
Assessing and treating lisps is largely similar in both child and adults, beginning with seeking professional help from a speech therapist. The only added challenge with adults is finding someone that you can practice with on your own time. Whether this is a spouse, family member, or friend, it’s important to have someone you trust provide honest feedback and encouragement so you can continue to improve on your own time outside of the sessions.
Expressable matches families with a certified speech therapist trained to effectively evaluate and treat speech impediments like lisps. All therapy is delivered online via face-to-face video conferencing.
Your child’s age and development will influence how your speech therapist interacts with them through these video chat capabilities.
Ages 0-3: Parents work directly with their speech therapist to learn cues and at-home strategies so they can confidently practice with their child outside the session and improve their communication.
Ages 3-6: Parents attend video sessions alongside their child so they both learn valuable skills from their speech therapist. Reinforcing these lessons outside the session will continue to promote at-home skill building.
Ages 7 and Up: Most children attend video sessions independently but parents are kept in the loop with updates and tips during each session.
Adults: Adults attend sessions by themselves, but are welcome to bring loved ones or family members as well.
As with all speech impediments, having your child practice once or twice a week with a speech therapist simply isn’t enough. Overcoming old habits takes constant reinforcement outside of the sessions. When parents are actively involved in their child’s speech development, and reinforce best practices and exercises at home, children make more progress in overcoming their communication obstacles.
While your speech therapist will provide personalized recommendations for at-home practice, here are a few tips and techniques you can start using immediately to help prevent a lisp from becoming more pronounced.
At Expressable, we're committed to improving outcomes and experiences for children and adults with speech therapy needs. Get connected with professional, licensed, vetted speech therapists from the comfort of your own home - and for less money than traditional therapy.
