Vocal Stereotypy

Repetitive, non-functional vocalizations that serve no apparent communicative purpose, commonly observed in individuals with autism spectrum disorder and other developmental disabilities. Vocal stereotypies may include repetitive humming, squealing, echolalia (repeating heard phrases without communicative intent), throat clearing, or production of unusual sounds. While these vocalizations may serve self-regulatory functions for the individual (such as sensory stimulation or anxiety management), they can interfere with social interactions, learning opportunities, and the development of functional communication skills. Interventions often aim to reduce vocal stereotypies while simultaneously increasing communicative vocalizations.
