Echolalia is the repetition of words, phrases, intonation, or sounds of the speech of others. Children and adults with autism often display echolalia in the process of learning to talk. Immediate echolalia is the exact repetition of someone else’s speech, immediately or soon after the child hears it. Delayed echolalia may occur several minutes, hours, days, or even weeks or years after the original speech was heard. Echolalia is sometimes referred to as “movie talk” because the child can remember and repeat chunks of speech like repeating a movie script. Echolalia was once thought to be non-functional, but is now understood to often serve a communicative or regulatory purpose for the child.
