Effects of talker variability on categorization of spectrally degraded vowels

Abstract

When a person listens to a context sentence with prominent higher frequencies, the subsequent vowel sound is more likely to be perceived as being of a lower frequency and vice versa. This is a spectral contrast effect (SCE). Recent work has shown that talker variability diminishes these SCEs. They were found to be smaller when 200 sentences were spoken by a different talker each
