Speech development is a fascinating journey, and along the way, children may encounter various challenges. One common speech issue is lisping, which can affect a child's ability to pronounce certain sounds clearly. Among the different types of lisps, frontal and lateral lisps are the most frequently observed. This blog aims to shed light on these two types of lisps, their characteristics, and how speech therapy can help.
What Are Lisps?
A lisp is a speech disorder that involves difficulty pronouncing sibilant sounds, particularly the “s” and “z” sounds. Lisps can lead to the production of these sounds in a way that may be perceived as unclear or incorrect. While many children may have a temporary lisp as they develop their speech skills, frontal and lateral lisps are specific types that can persist beyond the typical age for sound development.
Frontal Lisp
Characteristics: A frontal lisp occurs when the tongue protrudes between the front teeth during the production of “s” and “z” sounds. This results in the sounds being produced with a “th” sound, so “soup” may sound like “thoup,” and “zoo” may sound like “zoo.”
Causes: Frontal lisps can be caused by several factors, including:
Tongue Thrust: Some children naturally have a tongue thrust habit, where the tongue pushes forward during speech.
Dental Issues: Malocclusion or missing teeth can contribute to a frontal lisp, as the positioning of the teeth affects how sounds are produced.
Developmental Factors: Many children experience a frontal lisp during early speech development; however, it should resolve as their speech skills mature.
Lateral Lisp
Characteristics: A lateral lisp occurs when the airflow is directed over the sides of the tongue instead of down the middle. This often results in a “slushy” or “wet” sound when producing “s” and “z” sounds. For example, “snake” may sound like “shnake.”
Causes: Lateral lisps can arise from:
Tongue Positioning: Children may not position their tongue correctly when trying to produce the “s” and “z” sounds, causing the air to escape laterally.
Mouth Breathing: Mouth breathing, often associated with allergies or nasal congestion, can contribute to incorrect tongue placement and speech production.
Habits: Some children develop a lateral lisp due to habits formed during speech or play, such as frequently pushing the tongue to the sides.
Addressing Frontal and Lateral Lisps in Speech Therapy
Speech therapy is a highly effective way to address frontal and lateral lisps. Here are some common strategies used by speech-language pathologists (SLPs):
Assessment and Individualized Plan: The first step is a comprehensive assessment to determine the type of lisp and the underlying factors contributing to it. Based on this assessment, SLPs develop personalized therapy plans.
Targeted Exercises: SLPs use specific exercises to help children practice correct tongue positioning and airflow for producing “s” and “z” sounds. This may include visual aids to demonstrate the correct tongue placement.
Auditory Discrimination Activities: Helping children distinguish between correct and incorrect sound production is vital. Activities that involve listening to and identifying sounds can improve their awareness and understanding.
Modeling and Repetition: SLPs often model the correct production of sounds and encourage children to repeat them. This practice helps reinforce proper articulation through repetition.
Use of Games and Interactive Activities: Incorporating games and fun activities keeps children engaged and motivated to practice. SLPs often use playful approaches to reinforce learning.
Parental Involvement: Involving parents in the therapy process is crucial for success. SLPs provide strategies and resources for home practice, ensuring consistent reinforcement outside of therapy sessions.
Conclusion
Frontal and lateral lisps are common speech issues that many children may experience during their development. Understanding the characteristics and causes of these lisps is essential for parents and caregivers to support their children effectively. With the help of speech therapy, children can learn to articulate sounds correctly, improving their communication skills and boosting their confidence. If you suspect your child may have a lisp, consulting a speech-language pathologist can be a valuable step toward effective resolution and improved speech clarity.
