| Abstract | Prior experience with a talker's speech contributes little to success in vowel identification. In a series of 3 experiments, adult listeners averaged only 12.9% errors on 15 vowels in /h-d/ syllables spoken in mixed order by 30 talkers (men, women, & children), & 17.0% errors on 9 vowels spoken in /p-p/ syllables by 15 talkers. When the /p-p/ test series was spoken by single talkers, errors decreased to 9.5%. Precursors mainly influenced listeners' response biases, rather than facilitating true improvements in vowel identifiability. These results did not support the hypothesis that point vowels provide listeners with unique information for normalizing a talker's 'vowel space.' Sentence context aids vowel identification by allowing adjustment to a talker's tempo, rather than to the talker's vocal tract. |
