Parents Also Ask

What is a speech sound disorder?▼

A speech sound disorder (SSD) is when a child has difficulty producing sounds correctly beyond the typical age. Unlike normal developmental patterns that resolve naturally, SSDs persist and may need therapy. An SLP can diagnose and treat SSDs.

How is speech sound disorder different from normal development?▼

Normal: A 2-year-old saying "tar" for "car" (fronting). Disorder: A 5-year-old still doing this. The difference is persistence beyond expected ages. If errors continue past typical resolution ages, it may be a disorder.

Can speech sound disorders be fixed?▼

Yes! With speech therapy, most children with speech sound disorders make significant progress. Early intervention is key. The younger the child starts therapy, the better the outcomes typically are.

What causes speech sound disorders?▼

Causes vary: some are unknown, others relate to hearing issues, oral-motor difficulties, or neurological factors. Many children have no identifiable cause. The good news is that cause doesn't determine outcome—therapy helps regardless.
