How to Get Rid of a Lisp

In this article, we are going to take a look at the intricacies of lisps and their impact on speech communication, especially in children. We'll explore what lisps are, how they develop in children, various therapy techniques for addressing them, and the different types of lisps that can affect speech.

Additionally, we'll discuss the concept of functional speech disorders and their significance. From the available programs for children with lisps to the possibility of addressing lisps from home, we'll provide insights and guidance to help you better understand and navigate the realm of lisps and speech improvement.

What Is A Lisp?

A Lisp Speaking Disorder, also known simply as a "lisp," is a speech disorder characterized by difficulties in pronouncing the sounds of certain letters or letter combinations. The most common type of lisp is the "interdental" or "dentalized" lisp, where the /s/ and /z/ sounds are produced with the tongue positioned against or between the front teeth. This results in a slushy or "slushy" sound.

Another type is the lateral lisp, where the /s/ and /z/ sounds are pronounced with air escaping over the sides of the tongue, resulting in a distorted or "wet" sound.

Lisps can be present in both children and adults and may emerge due to various factors, including developmental issues, anatomical differences in the oral cavity, or a lack of proper speech muscle coordination. Speech therapy and intervention by a licensed speech-language pathologist are often used to address and treat lisps. Through exercises, techniques, and targeted practice, individuals with a lisp can improve their speech clarity and achieve more accurate sound production, enhancing their overall communication skills.

How Does a Lisp Develop in Children?

A lisp in children typically develops as a result of difficulties in acquiring and coordinating the correct tongue and lip movements necessary for accurate speech sound production. There are a few common developmental factors that can contribute to the emergence of a lisp in children:

Speech Sound Development: Children go through a process of learning and mastering speech sounds as they grow. Some children may naturally struggle with certain sounds, including the /s/ and /z/ sounds, due to the complex tongue and lip positioning required for their production.

Oral Anatomy: Anatomical differences in the oral cavity, such as the size and shape of the palate, tongue, and teeth, can influence speech sound production. For example, if a child has a low or uneven palate, it might make it more challenging to place the tongue correctly for producing sounds like /s/ and /z/.

Oral Habits: Prolonged use of pacifiers, thumb sucking, or other oral habits can impact the development of proper speech patterns. These habits might affect the positioning of the tongue and the muscles involved in speech production.

Articulation Patterns: Children often imitate speech models from their environment, including family members, peers, and media. If they hear incorrect or inconsistent models for producing speech sounds, it might lead to the development of incorrect articulation patterns, including lisping.

Auditory Perception: Some children might have difficulty accurately perceiving and distinguishing between speech sounds. This can make it challenging for them to monitor and correct their own speech errors.

It's important to note that lisps are relatively common in young children as they navigate the complexities of speech sound acquisition. Many children naturally outgrow lisping as their speech muscles mature and their oral coordination improves.

However, if a lisp persists beyond a certain age (typically around the age of 4-6), or if it is causing communication difficulties or affecting a child's self-esteem, it's advisable to seek the guidance of a licensed speech-language pathologist. Speech therapy can provide structured interventions and exercises to help children develop the correct speech patterns and overcome lisping issues. Early intervention is key to addressing speech sound disorders effectively.

What Are Some Therapy Techniques for Getting Rid of A Lisp?

Speech-language pathologists use a variety of therapy techniques to help individuals overcome lisping and improve their speech sound production. The specific techniques employed may vary based on the individual's age, the type of lisp, and their specific needs. Here are some common therapy techniques for addressing lisping:

1. Auditory Discrimination: This technique focuses on training the individual to accurately hear and distinguish between correct and incorrect speech sounds. By developing a heightened awareness of the differences in sound production, individuals can work toward self-correction.

2. Tongue Placement Exercises: Since lisping often involves incorrect tongue placement, therapists use exercises that guide the individual in positioning their tongue correctly for producing /s/ and /z/ sounds. Visual and tactile cues may be used to help the individual feel the correct tongue placement.

3. Oral-Motor Exercises: These exercises target the muscles involved in speech production. Activities that strengthen and improve muscle coordination in the lips, tongue, and jaw can help individuals achieve clearer speech.

4. Sound Imitation: Speech-language pathologists provide accurate models of the /s/ and /z/ sounds, which the individual then imitates. This helps them learn the proper articulatory movements required for correct sound production.

5. Syllable Drills: By practicing the target sounds in different syllable combinations (e.g., "sa," "se," "si," "so," "su"), individuals can improve their ability to produce the sounds correctly across various contexts.

6. Word and Sentence Practice: Gradually, individuals work on producing target sounds in words and sentences, incorporating them into meaningful communication. This helps bridge the gap between isolated sound practice and real-life speech.

7. Visual Feedback: Some therapists use tools like mirrors or video recordings to provide visual feedback to individuals, allowing them to see their mouth movements and make adjustments as needed.

8. Desensitization Techniques: Individuals with lisps might have developed negative emotions or self-consciousness about their speech. Therapy sessions can incorporate activities to help build confidence and reduce anxiety related to speech.

9. Home Practice: Consistent practice outside of therapy sessions is crucial for progress. Therapists often provide exercises and activities for individuals to practice at home, ensuring continuous improvement.

10. Cognitive Techniques: For older children and adults, cognitive strategies can be employed to enhance awareness of their speech patterns, encourage self-monitoring, and facilitate self-correction.

It's important to note that therapy techniques are tailored to the individual's specific needs and progress. A licensed speech-language pathologist will conduct an assessment to determine the most suitable approach and design a personalized plan to address the lisp and improve overall speech clarity.

How Does a Therapist Evaluate A Lisp?

When evaluating a lisp, a speech-language pathologist follows a comprehensive assessment process to understand the individual's speech patterns and determine the underlying factors contributing to the lisp. The assessment aims to identify the specific type of lisp, the severity of the speech sound disorder, and any associated factors that might be influencing the individual's speech production.

The assessment typically begins with a case history interview, where the therapist gathers information about the individual's developmental history, speech and language milestones, any known medical or anatomical factors, and the individual's own perception of their speech difficulties. This information helps provide context and insights into the potential causes of the lisp.

The speech-language pathologist then conducts various standardized and non-standardized assessments. These assessments might involve having the individual produce specific speech sounds in various word and sentence contexts. For lisping, the focus would be on evaluating the /s/ and /z/ sounds in different positions within words (initial, medial, final) and in various combinations. The therapist listens for the type of lisp (interdental, lateral, or other variations), the accuracy of sound production, and any patterns of substitution or distortion.

Additionally, the therapist may assess the individual's ability to discriminate between correct and incorrect speech sounds auditorily, as well as their awareness of their own speech errors. Observations of the individual's oral-motor movements, tongue placement, and overall oral coordination may also be included in the evaluation.

Depending on the individual's age and communication skills, the therapist might use play-based or interactive activities to engage the individual during the assessment process. This can help create a comfortable environment for accurate observations.

Following the assessment, the speech-language pathologist analyzes the gathered information to determine the type and severity of the lisp, as well as any contributing factors. This analysis guides the development of an individualized intervention plan tailored to the individual's needs. The therapist considers factors such as the individual's age, cognitive abilities, motivation, and any potential emotional or social impact of the lisp.

Overall, the evaluation process is thorough and multidimensional, allowing the therapist to gain a holistic understanding of the individual's speech production and design an effective treatment plan to target the lisp and support improved speech clarity.

Is Having a Lisp Normal?

Having a lisp is relatively common, especially among young children who are still developing their speech sounds. Lisping is considered a normal part of speech development for many children, and in most cases, it naturally resolves as they mature and their speech muscles and coordination improve. It's estimated that around 5-10% of children exhibit some form of lisping during their speech development.

However, the term "normal" in this context has a wide range. While some degree of lisping might be considered a normal part of speech development, persistent or severe lisping beyond a certain age (typically around 4-6 years old) might warrant attention and intervention. If a lisp is significantly affecting a person's ability to communicate clearly, impacting their self-esteem, or causing difficulties in social interactions, it's advisable to seek guidance from a licensed speech-language pathologist.

In some cases, individuals might continue to exhibit a lisp into adulthood. While less common, lisping can persist due to various factors, including incomplete speech sound development during childhood, lack of intervention, or the presence of other speech-related issues. For these individuals, seeking therapy can still lead to improvements in speech clarity and confidence.

In summary, while lisping is not uncommon in children's speech development, it's important to monitor its progression. If a lisp persists beyond a certain age or is causing communication challenges, seeking professional advice and, if necessary, speech therapy, can help address the issue and support improved speech sound production.

Can I Fix My List from Home?

While it's possible to work on improving a lisp from home, it's generally recommended to seek guidance from a licensed speech-language pathologist (SLP) to ensure effective and safe progress. An SLP can provide a thorough assessment, design a personalized treatment plan, and offer expert guidance to address the specific type of lisp and its underlying causes. However, here are some general tips and exercises that you can consider as a starting point:

Mirror Practice: Using a mirror, observe your tongue and lip movements while attempting to produce the /s/ and /z/ sounds correctly. Compare your movements to videos or visual guides of correct articulation.

Tongue Awareness: Develop awareness of your tongue placement. Try gently placing the tip of your tongue behind your upper front teeth (alveolar ridge) when producing the /s/ and /z/ sounds.

Syllable Repetition: Practice saying syllables that incorporate the target sounds, such as "sa," "se," "si," "so," "su." Focus on clear and accurate sound production.

Sentence Practice: Incorporate the /s/ and /z/ sounds into short sentences. Choose sentences that contain various word positions (initial, medial, final) to practice different contexts.

Minimal Pairs: Work with minimal pairs, which are pairs of words that differ by only one sound, such as "sip" and "zip." Practicing these pairs can help you distinguish between correct and incorrect sound production.

Breath Control: Focus on controlled airflow while producing the /s/ and /z/ sounds. Avoid excessive airflow or breathiness that might contribute to lisping.

Record Yourself: Record your speech practice and listen for improvements. This can help you monitor your progress and identify areas for further refinement.

Online Resources: Utilize online videos and tutorials created by reputable speech professionals. They may provide visual and auditory guidance for practicing the correct articulation.

Remember, while home practice can be helpful, a lisp can have underlying causes that may require personalized guidance and correction techniques. Seeking the expertise of a licensed speech-language pathologist is recommended to ensure proper assessment, tailored strategies, and effective progress toward clear speech. An SLP can also provide feedback and adjust your practice as needed, leading to more successful outcomes in addressing your lisp.


In conclusion, lisps are speech sound disorders that can impact individuals of various ages, from children to adults. Understanding the development, types, and potential causes of lisps provides valuable insights into effective intervention strategies. While lisps are relatively common in childhood speech development, early identification and professional guidance can contribute to successful outcomes.

Speech therapy techniques, whether through individual sessions, group programs, or online resources, play a crucial role in helping individuals overcome lisping and enhance their communication skills. Remember that seeking assistance from a licensed speech-language pathologist ensures personalized assessment and targeted guidance tailored to each individual's needs. With the right support, lisps can be effectively addressed, leading to clearer speech and improved self-confidence in communication.
