Echolalia is the repetition of words, phrases, or sentences spoken by others. It is common in autism and occurs in two forms: immediate echolalia (repeating something just heard) and delayed echolalia (repeating something heard hours, days, or weeks earlier — often from TV shows, books, or conversations). While echolalia was once dismissed as meaningless, research shows it often serves communicative functions — a child may echo a phrase to request something, protest, affirm, or process language. For example, a child who says 'want some juice?' when thirsty is using delayed echolalia to make a request. Speech-language pathologists can help families interpret echolalia and shape it toward more conventional communication.
Understanding echolalia helps families and therapists set meaningful speech goals. It is relevant to IEP speech services and waiver-funded speech-language therapy authorizations.
