Variability Among Ten Talkers of Word Intelligibility in Noise

Abstract

It may not be good practice to depend upon a single voice in assessing the performance of a communication system. Even when each of ten talkers with dialect-free speech, who spoke at a comfortable level, were equated for acoustic intensity, one talker yielded a performance of 75.5% words correct, another only 47.5%. It would be necessary to take the average intelligibility of any five of these talkers properly to assess a communication system. A great deal of research needs to be done in studying the acoustic and perceptual cues which render a particular voice highly intelligible in noise.
