Computer Feedback System

A technology system that detects a user's behavior — such as vocalizations, movements, or physiological signals — and provides immediate audio, visual, or haptic responses mapped to that behavior. In speech and communication interventions, computer feedback systems translate vocalizations into alternative sensory modalities in real time, allowing users to perceive their own speech through visual displays (shapes, colors, animations) or modified audio (echoes, musical rewards). CFS has been shown to impact the communication behavior of both neurotypical individuals and people with disabilities, and is particularly studied in autism interventions where it can encourage speech development by making the consequences of vocalization more salient and engaging.
