Factoral Analysis of the Delayed Speech Feedback Phenomenon

Abstract

Two experiments, employing a total of 388 subjects, were conducted to study factors influencing performance on the delayed speech feedback task. The rate of presenting reading material, the intensity, and length of delay of speech feedback served as independent variables. A linear relation was found between performance on the feedback task and intensity of the delayed signal. There was an interaction between intensity and delay time of the speech feedback, clearly demonstrating that various delays are differentially effective only at high intensity levels. That the role of delay is more than a simple interference factor produced by background noise was also demonstrated.
