Terminology & Definitions
Clear definitions of common speech disorders
Speech Delay
A condition where a child's speech development falls significantly behind typical milestones for their age. Children with speech delay may have fewer words, difficulty combining words, or trouble being understood.
Language Disorder
A communication disorder affecting a child's ability to understand language (receptive) or express themselves (expressive). Unlike speech delay, language disorders typically don't resolve without intervention.
Articulation Disorder
A speech sound disorder where a child has difficulty producing specific sounds correctly, such as substituting 'w' for 'r' (saying 'wabbit' instead of 'rabbit').
Childhood Apraxia of Speech (CAS)
A motor speech disorder where the brain has difficulty coordinating the movements needed for speech. CAS requires specialized treatment approaches and typically longer-term therapy.
Stuttering
A fluency disorder characterized by interruptions in the flow of speech, including repetitions, prolongations, or blocks. Stuttering is a neurological condition, not caused by anxiety.
