Speech-sound development
Speech-Sound Age Chart
A gentle, descriptive guide to the typical age by which many English-speaking children produce each speech sound. Ages vary; this is not a test.
This chart shows a rough, typical age by which many English-speaking children produce each consonant sound clearly. It describes typical ages — it is not a test and cannot tell you whether an individual child needs support. Children vary widely, and a later sound is not a problem by itself. Ages summarised from Crowe & McLeod (2020), Children’s English Consonant Acquisition in the United States.

Worried about a specific sound? See when to talk to a speech-language pathologist — and remember an app or chart can’t interpret this for you.
These word lists are for calm at-home practice and general information. They are not a diagnosis or an assessment. Whether a sound is “on time” depends on age, language background and the whole communication picture — a speech-language pathologist can help you read it; an app or a list cannot.
Practise these at home
SpeechSeed groups words by the sound they help with and lets a grown-up — not an algorithm — judge each whole-word try. A practice and support tool, not a replacement for a speech-language pathologist.
