Orientation to Speech Sound

A series of experiments are described in support of a model of speech recognition. The vowel /a/ from a complex signal generator was presented binaurally, each ear channel being independently controlled for signal intensity and duration of a medial silent interval (0–90 msec), such that a fused percent /a/, /ara/, /ala/, or /a-a/ resulted in the center, or to one or other side of auditory space. Analysis of categorical response probability and lateralization of a percept as functions of duration of the interval and interaural intensity difference enabled the functional levels and operations represented by the model to be substantiated.
