APA Dictionary of Psychology

a technique of auditory feedback in which speakers listen through headphones to their own speech, which is heard a short time after it is spoken. It is one of several techniques that may be used to induce greater fluency and clearer articulation in those with various speech and language disorders, particularly in those who stutter. Paradoxically, however, the delay in DAF has also been found to cause dysfluency in normally fluent speakers.
