The repetition of single speech sounds under delayed auditory feedback.

Abstract

Three experiments were carried out to determine the effect of delayed auditory feedback (DAF) on the rate of repetition of single speech sounds. Other variables investigated were variation in repetition rate among speech sounds under DAF, and the effect of the subject's sex on repetition rate. Subjects were found to repeat sounds significantly fewer times under DAF. There was no significant variation among sounds repeated under DAF, nor was there a sex effect. Since the major finding was in the opposite direction to that reported by Chase (1958), a fourth study was carried out to investigate a possible cause of this discrepancy.
