Singapore English, language use, proficiency, consonants, age of acquisition (AoA)Abstract
The present study investigates the extent to which age of acquisition (AoA), English language proficiency and use influence consonant perception in Singapore English (SgE). Consonantal pairs of interest were presented in a gating paradigm to determine the amount of linguistic information participants required for accurate consonant identification as a measure of perceptual acuity. Only the [th]–[?] and [t]–[?] phonetic contrasts emerged sensitive to differences in AoA of English, with the early AoA group outperforming the late AoA group. Language proficiency and use did not significantly influence consonant perception. The findings are discussed in light of how AoA may interact with the universal difficulty and distributional regularities of speech contrasts to affect speech processing. Future studies should investigate a wider range of SgE speakers and identify distributional regularities of speech sounds to gain a more comprehensive picture of the factors that influence consonant perception in SgE.
