Abstract

Cochlear implant (CI) and normally hearing (NH) listeners' recognition of periodically interrupted sentences was investigated. CI listeners' scores declined drastically when the sentences were interrupted. The NH listeners showed a significant decline in performance with increasing spectral degradation using CI-simulated, noise-band-vocoded speech. It is inferred that the success of top-down processes necessary for the perceptual reconstruction of interrupted speech is limited by even mild degradations of the bottom-up information stream (16 and 24 band processing). A hypothesis that the natural voice-pitch variations in speech would help in the perceptual reconstruction of the sentences was not supported by experimental results.
