Speech Sound Disorder

To define Speech Sound Disorder: Persistent difficulty producing speech sounds correctly, reducing intelligibility and limiting communication effectiveness.

Overview

Description

Speech Sound Disorder (SSD) is characterized by persistent difficulties with speech sound production that interfere with speech intelligibility or prevent verbal communication of messages. Errors exceed what is expected for age or developmental level, cause functional impairment, and are not attributable to congenital or acquired conditions (e.g., hearing loss, structural anomalies, neurological disorders).

Prevalence

Estimated 3–5% of preschool and early school-age children; more common in males.

Age of Onset

Symptoms typically evident by ages 3–4 when speech should be increasingly intelligible to unfamiliar listeners.

DSM-5 Code

315.39

ICD-10 Code
