Ages and Stages: Speech
This chart shows the range of ages at which children typically acquire consonant sounds. The end of each bar
represents the age by which most children have achieved each sound (Adapted from Sander, E.K. When are
speech sounds learned? Journal of Speech and Hearing Disorders, 1972, 31, 62. Some examples of consonant
blend acquisition have been added from Templin Darley, 1947).
