Abstract

This study examined the vowel quality in lexical stress noun and verb pairs
produced by control, RHD and LHD subjects. A perceptual analysis of the errors in both
groups revealed errors in articulatory positioning relative to vowel height and to a lesser
degree vowel fronting. However, substitutions between tense and lax vowels also suggest
that a speech timing deficit may be present where variations in vowel length influenced the
perception of the vowels. Acoustic analyses of the F1 and F2 formant frequencies will be
performed to determine if there is a relationship to the perceived vowel substitutions.
