Click
Monitoring and the Perceptual Segmentation of Speech Sequences
K. Fukuda |
Two
experiments are reported in which subjects respond to a click placed
on a speech sequence, and their responses are analyzed by taking
response bias into consideration. In the first experiment, it is
shown that clicks objectively placed around the designed boundary
of sentences which is added an acoustic feature, are subjectively
monitored in or toward that boundary, as well as the major syntactic
boundary. In the second experiment, it is shown that such clock displacement
occurs, even when the speech materials are meaningless Letter sequences.
It is concluded that speech sequences are perceptually segmented
by using both acoustic and syntactic cues. It is suggested that sentence
perception should involve different processes from those of sentence
reproduction in the click localization task.
