 Delayed auditory feedback

Delayed auditory feedback (DAF) is a phenomenon and a technique used primarily in speech therapy, research, and various communication studies. It occurs when a person's speech is fed back to them with a slight delay—usually measured in milliseconds. This delay can affect how individuals perceive and produce speech. In a controlled environment, DAF is often used as a tool to help individuals who stutter. The delayed feedback can disrupt the normal flow of speech, which may lead to changes in speech patterns.
