Speech Sound Disorders

When a child's speech is difficult to understand — by family, teachers, or peers — it can affect their confidence, their friendships, and their success in the classroom. At ThinkSpeech Therapy in Ashburn, VA, we specialize in identifying and treating speech sound disorders in children and adults, using evidence-based approaches tailored to each individual client.

Articulation Disorders

Who it's for: Children and adults who have difficulty producing specific speech sounds correctly.

Articulation disorders occur when the speech mechanisms (tongue, lips, jaw, and palate ) are not moving in the precise way needed to produce clear sounds. A child might say "wabbit" instead of "rabbit," or "thun" instead of "sun." While some sound errors are a completely normal part of early speech development, errors that persist past the expected age warrant evaluation.

Signs to look for:

  • Substituting one sound for another (e.g. "w" for "r")

  • Distorting sounds so they sound unclear

  • Omitting sounds from words

  • Speech that is difficult to understand, especially for unfamiliar listeners

  • Frustration or reluctance to speak in social situations

Phonological Disorders

Who it's for: Children whose speech errors follow consistent patterns that affect overall clarity.

Phonological disorders involve patterns of sound errors rather than difficulty with individual sounds. A child with a phonological disorder understands the rules of language, but their speech system hasn't yet organized the sound patterns of English correctly. For example, they may consistently leave off the final sound in words ("boo" for "boot") or simplify consonant clusters ("top" for "stop"). These patterns can make a child very difficult to understand, even for familiar listeners.

An accurate diagnosis of whether a child has an articulation disorder, a phonological disorder, or both is critical because treatment approaches differ significantly. At ThinkSpeech, we use the Cycles Approach for phonological disorders, which targets error patterns systematically and has been shown to improve overall speech intelligibility more efficiently than sound-by-sound remediation.

Signs to look for:

  • Consistently leaving sounds off the ends of words

  • Simplifying consonant clusters ("poon" for "spoon")

  • Substituting whole classes of sounds (e.g. all back sounds like "k" and "g" replaced with front sounds like "t" and "d")

  • Speech that is difficult to understand even for family members

  • Multiple sound errors that follow a pattern

Childhood Apraxia of Speech (CAS)

Who it's for: Children who have difficulty planning and coordinating the movements needed for speech.

Childhood Apraxia of Speech is a motor speech disorder where the brain has difficulty sending the right signals to the muscles used for speaking. Children with CAS know exactly what they want to say, but struggle to get the words out consistently. CAS requires early, intensive, and highly specialized therapy and we use DTTC to support children with CAS.

Signs to look for:

  • Limited or no babbling as an infant

  • Difficulty combining sounds and syllables

  • Inconsistent speech errors — saying a word correctly once but differently the next time

  • Groping movements of the mouth when trying to speak

  • Better understanding of language than ability to express it

  • Regression in speech skills under stress or fatigue
