When speaking under conditions of delayed auditory feedback, we hear what we have said a short time after we have said it. Most normally fluent speakers become highly disfluent when exposed to DAF and many stutterers experience decreased stuttering under DAF. DAF can also be used clinically both to help establish fluency as well as control/modify the stuttering.
