Repetitive speech is an extremely common part of language development, and is commonly seen in young toddlers who are learning to communicate. By the age of 2, most children will start mixing in their own utterances along with repetitions of what they hear. By age 3, most children’s echolalia will be minimal at most.

Echolalia is different from Tourette syndrome, where a speaker may suddenly yell or say random things as part of their tic. In this case, they speaker has no control over what they say or when they say it.

The main symptom of echolalia is the repetition of phrases and noises that have been heard. It can be immediate, with the speaker repeating something right away after hearing it. It can also be delayed, with the speaker repeating something hours or days after hearing it.

Other signs of echolalia may include frustration during conversations, depression, and muteness. A person with echolalia may be unusually irritable, especially when asked questions.

Functional echolalia is attempted communication intended to be interactional, acting as communication with another person. Examples include:Turn taking: The person with echolalia uses phrases to fill an alternating verbal exchange.Verbal completion: Speech is used to complete familiar verbal routines that are initiated by others. For example, if people with echolalia are asked to complete a task, they might say “good job!” while completing it, echoing what they’re used to hearing.

Rehearsal: The speaker may utter the same phrase softly to themselves a few times before responding in a normal voice. This may be practice for the coming interaction.Self-direction: People might use these utterances to walk themselves through a process. If they’re making a sandwich, for example, they might tell themselves to “Turn on water. Use soap. Rinse hands. Turn off water. Dry hands. Get bread. Put bread on plate. Get lunch meat,” and so on until the process is completed.

People with echolalia repeat noises and phrases that they hear. They may not be able to communicate effectively because they struggle to express their own thoughts. For example, someone with echolalia might only be able to repeat a question rather than answer it. In many cases, echolalia is an attempt to communicate, learn language, or practice language.
