Dealing with Lisp Speech :Know its types and Treatments

lisp speech

Having clear speech is an important part of being a confident speaker. Speech problems like lisp can significantly impact an individual's confidence and social interactions. Lisp speech can stem from various factors, including physical anomalies, neurological disorders and psychological factors. Understanding these problems is the first step towards effective solutions.

In this article, we shall talk about one of the most common speech problems- Lisp, its causes, types and treatment options. Stay tuned to the end of the blog to find out a way to permanently get rid of lisp in a non-invasive and convenient manner.

What is a Lisp?

A lisp is a speech abnormality where the individual finds it difficult to pronounce 's' and 'z' sounds, leading to unclear or distorted speech. This common speech issue can happen to anyone and can influence personal and professional interactions. Let us dive deeper into the subject and understand its causes, types and possible treatment methods.

Causes of Lisp Speech

- Developmental Issues

As children develop speech skills, they may temporarily exhibit a lisp. This is a normal part of speech development. However, if the lisp speech continues to hamper one’s communication beyond the age where speech typically stabilises (usually around the age of 4-5 years), it may reflect the need for professional help.

- Neurological Disorders

Various neurological conditions can impact the muscles and nerves involved in speech, leading to a lisp. Disorders such as cerebral palsy, traumatic brain injury or stroke can affect the control of the tongue and mouth.

- Hearing Impairments

A person who experiences hearing loss or impairments may be unable to hear certain sounds and hence find it difficult to pronounce them.

- Psychological Factors

In some cases, a lisp can be psychogenic, meaning it originates from psychological factors. Stress, anxiety or traumatic events can sometimes manifest in speech disorders like lisping, especially in adults.

Types of Lisps

- Interdental Lisp

This is one of the most common types of Lisp speech. In an interdental lisp, the tongue protrudes between the front teeth when attempting to produce the 's' and 'z' sounds, causing them to sound more like 'th'.

- Dentalised Lisp

When the tongue presses against the front teeth while pronouncing ‘s’ and ‘z’ sounds, it can be termed a dentalised lisp. This contact of teeth and tongue disturbs the airflow leading to a muffled or unclear pronunciation.

- Lateral Lisp

A lateral lisp is more complex and often considered one of the harder types to treat. In this case, the air flows over the sides of the tongue rather than directly through the middle of the mouth when making 's' and 'z' sounds. This creates a wet, slushy sound and can significantly affect speech clarity.

- Palatal Lisp

In a palatal lisp, the mid-section of the tongue comes in contact with the soft palate, or the roof of the mouth, far behind the teeth, while producing 's' and 'z' sounds. This unusual tongue placement alters the sound, often making it more muffled and less distinct.

Impact of Lisp on Communication

Having unclear speech can hinder clear communication. This can make the individual under confident in social, professional and even personal interactions. It can lead to self-consciousness, social anxiety, stage fright and impact one's overall quality of life.

Age Factor in Lisp Correction

While lisp speech can be corrected at any age, early intervention is key in correcting a lisp. While it is easier to treat in children due to their developing speech patterns, adults can also effectively address a lisp with proper therapy and dedication.
