Speech Sound Disorders

Speech-language pathologist and child practicing speech sounds during play-based speech therapy

Speech sound disorders can affect a child’s ability to produce sounds clearly or use speech sounds correctly in words.

If your child is hard to understand, leaves out or substitutes sounds, has a lisp, or struggles with sounds like /r/ or /s/, a speech-language pathologist can help determine whether their speech is developing as expected. Lotus Speech & Language Therapy provides individualized, play-based pediatric speech therapy in Austin for articulation disorders, phonological disorders, and motor speech disorders.

What are Speech Sound Disorders?

Speech sound disorders affect how a child produces and uses sounds in words. Difficulties may involve the production of individual speech sounds, patterns of sound errors that affect multiple sounds, or the planning and coordination of the movements needed for speech.

Articulation Disorders

Articulation refers to the way the lips, tongue, teeth, and jaw work together to produce individual speech sounds. An articulation disorder occurs when a child has difficulty producing one or more specific sounds accurately beyond the age when those sounds are expected to develop.

Articulation errors may include substitutions, omissions, additions, or distortions of individual speech sounds.

Phonological Disorders

Phonological disorders occur when a child continues to use phonological processes, or predictable patterns of sound errors, beyond the age when they are typically expected to resolve. These patterns can affect multiple sounds and words and may significantly reduce speech intelligibility.

Common phonological processes include fronting (“tat” for “cat”), stopping (“tun” for “sun”), final consonant deletion (“ca” for “cat”), and cluster reduction (“poon” for “spoon”).

Motor Speech Disorders

Motor speech disorders affect the planning, coordination, or execution of the movements needed to produce speech. A child may know what they want to say but have difficulty coordinating the precise movements and sequences required to produce sounds, syllables, and words clearly and consistently.

Motor speech disorders include childhood apraxia of speech (CAS) and dysarthria.

When Should I Consider a Speech Sound Evaluation?

Some speech sound errors are a typical part of development. A speech sound evaluation may be recommended when errors persist beyond the age they are expected to resolve, significantly affect how well a child is understood, or begin to impact everyday communication.

Consider an evaluation if your child:

is frequently difficult for family members, teachers, peers, or unfamiliar listeners to understand
has a frontal or lateral lisp
continues to have difficulty producing sounds that are expected for their age
produces words or speech sounds inconsistently
uses persistent phonological processes or leaves sounds or syllables out of words
becomes frustrated, embarrassed, or avoids speaking because they are not being understood

Speech Sound Evaluations

A speech sound evaluation looks beyond which sounds a child can or cannot say. The SLP assesses the types and patterns of speech sound errors, overall intelligibility, sound production across words and contexts, stimulability, and consistency of productions. When appropriate, oral structures and motor speech skills may also be evaluated to better understand the nature of the child’s speech difficulty.

The results help determine whether a child’s speech is developing as expected, identify the type of speech sound difficulty present, and guide individualized treatment recommendations.

Individualized Speech Therapy for Speech Sound Disorders

Speech therapy for speech sound disorders is individualized based on the type of speech difficulty, the sounds or patterns affected, and your child’s specific needs. Treatment may focus on learning to produce individual speech sounds, reducing phonological processes, or improving the planning and coordination of movements for speech.

At Lotus Speech & Language Therapy, evidence-based treatment strategies are incorporated into engaging, play-based activities. Games, books, toys, and your child’s interests are used to provide meaningful opportunities to practice speech sounds, improve speech intelligibility, and help new skills carry over into everyday communication.
