Acquisition of Voice Onset Time for Voiced Plosives of English by Adult Learners of Balochistan

Abstract

This study focuses on two experiments conducted with Eastern and Western Balochi speakers. In Eastern Balochi, voiceless stops have aspirated features, but in Western Balochi, they are unaspirated. Eighty-four native speakers of both dialects of Balochi participated in this study. Participants of the first experiment produced words of their L1 in a picture naming task, and those of the second experiment read words in English. VOTs of the L1 and L2 voiced stops elicited from recordings of the productions. Results show that speakers of Western Balochi transfer their L1 negative VOTs to L2 English-voiced stops. However, Eastern Balochi speakers produce English-voiced stops with VOTs, significantly different from their L1 VOTs. Though they could not produce English-voiced stops with native-like accuracy, they produced English stops with significantly longer pre-voicing duration than their L1-voiced stops. Therefore, the study concludes that speakers of those languages with stops with negative VOT ranges face more difficulty acquiring L2 voiced stops of short-lag positive VOTs than those learners whose L1 does not have such stops. The speech learning model is used in this study to analyze all results.
