Abstract
Vowel normalization in speech perception was investigated in three experiments.The range of the second formant in a carrier phrase was manipulated and thisaffected the perception of a target vowel in a compensatory fashion: A low F2 rangein the carrier phrase made it more likely that the target vowel was perceived as afront vowel, that is, with a high F2. Recent experiments indicated that this effectmight be moderated by the lexical status of the constituents of the carrier phrase.Manipulation of the lexical status in the present experiments, however, did notaffect vowel normalization. In contrast, the range of vowels in the carrier phrase didinfluence vowel normalization. If the carrier phrase consisted of mid-to-high frontvowels only, vowel categories shifted only for mid-to-high front vowels. It is arguedthat these results are a challenge for episodic models of word recognition.
