Temporal effect on the perception of continuous speech and a possible mechanism in the human auditory system

Hisao Kuwabara

Previous study suggests that a certain mechanism which makes acoustically uncertain words clear via contextual information exists in the process of human speech recognition. This mechanism is probably the most important one and plays a central role in the human speech recognition. This study has been conducted to investigate, through perceptual experiments, on how the mechanism works as a continuous speech proceeds and where it is located in the human auditory system. A dichotic fusion experiment has been conducted using two types of continuous three-vowel sequences. The fusion actually took place when the formants of the two stimuli were the same or very close to each other. A possible explanation was given under the working hypotheses postulated for this study.
