Speech / language delay
Slower-than-expected speech or language development, affecting roughly one in ten preschool children, assessed to distinguish an isolated delay from a broader developmental profile.
What it is
Speech and language delay describes slower-than-expected development of speech sounds, vocabulary, or the ability to understand and use language, affecting an estimated one in ten preschool children. Assessment distinguishes an isolated delay from a broader developmental profile (such as autism or global developmental delay) before therapy begins.
Common symptoms & concerns
- Assessment scores modestly below age expectation, often responsive to short-course therapy and home strategies
- A clearer gap from age expectation across expressive and/or receptive language
- Minimal or unintelligible speech, or very limited functional communication, in more significant presentations
- Recognised red flags: no babbling by 12 months, no single words by 16 months, no two-word combinations by 24 months, or loss of previously acquired language at any age
Assessment & care
Assessment approach
Assessment distinguishes an isolated speech/language delay from a broader developmental profile before a therapy plan is finalised, since the two are managed differently.
In-scope care
In-scope care includes speech therapy following a structured communication assessment, with parent-training available to reinforce communication strategies at home. Clinic-based therapy builds the specific skill while parent-coaching multiplies practice opportunities throughout the child's week.

Related questions
Recognised red flags include no babbling by 12 months, no single words by 16 months, no two-word combinations by 24 months, or loss of previously acquired language at any age; any of these warrants an assessment.
No. Speech and language delay can occur in isolation or as part of a broader developmental profile, which is exactly why assessment distinguishes between them before therapy begins.
Yes, parent-training to reinforce communication strategies at home is a core part of the plan, since most of a child's day-to-day language exposure happens outside the therapy room.
