Abstract : Forty-eight speakers received the messages they were to impart to listeners in a face-to-face situation. For 24 of them the aural channel was delayed 0.23 second from that of the visual. The experimental design yielded criterion scores applicable to the reduction by an analysis of variance. The effect of dissynchrony of the aural-visual signals upon the speakers was not to change the intelligibility of speech or the sound pressure level of voice. There was a significant change, namely, lengthening the time of phrase duration. (Author)
