How Can a Lisp Be Fixed With Speech Therapy?
A lisp is one of the most common speech disorders, especially in children. It occurs when the tongue pushes against or comes between the teeth during speech, affecting sounds like "s" and "z." While a lisp can impact clarity and confidence, the good news is that it is highly treatable with speech therapy. In this blog, we will explore how a lisp develops, the role of speech therapy in correcting it, and practical strategies to support individuals in improving their speech.
Understanding Lisp
A lisp is not just a minor speech quirk; it is a speech disorder that may result from:
Tongue placement issues: incorrect positioning of the tongue while speaking
Oral-motor difficulties, challenges with tongue and lip movements
Dental problems, such as misaligned teeth can affect speech
Developmental delays some children develop speech sounds later than their peers
Lisping can be categorized into different types:
The tongue protrudes between the teeth in an interdental lisp.
Dentalized Lisp the tongue presses against the teeth
Air passes over the sides of the tongue during a lateral lisp, producing a slushy sound.
Palatal Lisp the tongue touches the soft palate instead of the correct position
Early intervention is critical because untreated lisping can affect communication skills, social interactions, and academic performance.
Role of Speech Therapy in Correcting a Lisp
Speech therapy is the most effective treatment for a lisp. A licensed speech-language pathologist (SLP) assesses the type and severity of the lisp and develops a personalized plan. The therapy focuses on teaching proper tongue placement, strengthening oral muscles, and enhancing speech clarity.
Key techniques used in speech therapy include:
Auditory discrimination exercises helping individuals hear the difference between correct and incorrect sounds
Tongue placement practice using visual cues, mirrors, or tactile feedback to position the tongue correctly
Repetitive sound drills practicing "s" and "z" sounds in isolation, syllables, words, and sentences
Oral-motor exercises strengthening lips, tongue, and jaw for better control
By combining these techniques, speech therapy gradually retrains the tongue and mouth to produce clear, accurate sounds.
Benefits of Speech Therapy for Lisp
Engaging in speech therapy for a lisp offers multiple benefits beyond speech correction:

Home Strategies to Support Lisp Correction
Speech therapy is most effective when combined with supportive home practice. Parents and caregivers can use these strategies:
Encourage slow, deliberate speech reduce rushing to allow proper tongue placement
Use mirrors help the child see tongue positioning while speaking
Read aloud together reinforce correct sound production
Positive reinforcement celebrates small improvements to maintain motivation
Practice minimal pairs words that differ by a single sound, like “sip” vs. “zip”
These activities complement professional therapy, ensuring faster and more consistent progress.
