Abstract

The purpose of this project was to assess the degree to which a patient, after 1 wk of experience, could adapt to 3.2-mm and 6.8-mm basal shifts in the representation of speech. Only small deficits in performance were found after practice after the 3.2-mm shift. After practice after the 6.9-mm shift, scores on tests that emphasized amplitude envelope cues returned to baseline levels. Scores on vowel and sentence tests that emphasized frequency-based cues remained poor. Scores for "place," however, showed some recovery. Vowel recognition may be the limiting factor in recognizing basally shifted speech.
