Children with autism will develop language and speech skills, but not up to a normal level of ability, and their progress is uneven. A child may have a strong vocabulary in an area of interest quickly. Also, a child may have a good memory for information just heard. Some children may be able to read words by the age of five, but will not be able to comprehend what they have read. Also, children do not respond to the speech of others and will not respond to their own names.
