Intelligibility of foreign-accented Lombard speech

Chi-Nin Li

Abstract


The Lombard reflex occurs when normal-hearing speakers modify their vocal effort while speaking under noisy conditions. Since research associated with the Lombard reflex was conducted mainly with native speakers, little was known about its impact on foreign-accented speech. This paper aims to examine the effects of masking noise on the intelligibility of Lombard speech produced by non-native English speakers using a sentence-transcription task and a sentence-verification task.
