| Abstract: | Five dichotic speech experiments were conducted with normal adult listeners in which the signal to one or both ears was degraded by manipulation of intensity, signal-to-noise ratio, or bandwidth parameters. Results suggest that: (1) performance of the ear (or ears) receiving the degraded signal can be predicted from the monaural identifiability of the stimuli, and (2) dichotic performance, at least in stop consonant-vowel tests, reflects an additive central process which combines speech information from the two ears. |
