Greek perception and production of an English vowel contrast: A preliminary study

Abstract

This study focused on language-independent principles functioning in acquisition of second language (L2) contrasts. Specifically, it tested Bohn’s Desensitization Hypothesis [in Speech perception and linguistic experience: Issues in Cross Language Research, edited by W. Strange (York Press, Baltimore, 1995)] which predicted that Greek speakers of English as an L2 would base their perceptual identification of English /i/ and /I/ on durational differences. Synthetic vowels differing orthogonally in duration and spectrum between the /i/ and /I/ endpoints served as stimuli for a forced-choice identification test. To assess L2 proficiency and to evaluate the possibility of cross-language category assimilation, productions of English /i/, /I/, and /ε/ and of Greek /i/ and /e/ were elicited and analyzed acoustically. The L2 utterances were also rated for the degree of foreign accent. Two native speakers of Modern Greek with low and 2 with intermediate experience in English participated. Six native English (NE) listeners and 6 NE speakers tested in an earlier study constituted the control groups. Heterogeneous perceptual behavior was observed for the L2 subjects. It is concluded that until acquisition in completely naturalistic settings is tested, possible interference of formally induced meta-linguistic differentiation between a ‘‘short’’ and a ‘‘long’’ vowel cannot be eliminated.
