Abstract

The purpose of this study was to determine how noise influences first language (L1) speech perception in noise in bilingual listeners with varying second language (L2) proficiency. The Korean Speech Perception in Noise (KSPIN) test was administered in three signal-to-noise ratio (SNR) conditions to two groups of Korean-English bilingual listeners with moderate and low proficiency in English. All bilingual participants acquired the L2 and arrived in the United States after puberty. Special efforts were made to recruit homogenous bilingual groups. The results indicated that speech perception in noise in L1 for bilingual listeners with higher L2 proficiency was affected more in the most negative SNR conditions in comparison to bilingual listeners with less L2 proficiency. This study demonstrated that adult bilingual listeners experience more difficulty processing L1 in noise as L2 proficiency increases.
