Previous studies have shown that although native listeners consistently outperform non-native listeners in listening comprehension tasks, both native and non-native listeners are sensitive to dialectal cues in target and masking speech when targets are presented in background babble of varying intensities. The present study examined the listening comprehension skills of 24 Korean-English bilingual listeners who were presented with sentence stimuli in two-talker babble. Stimuli and babble were comprised of two dialects, General American English (GAE) and Southern American English (SAE), which were systematically varied throughout testing at three signal-to-noise ratios (SNRs). In a previous study by Fox, Jacewicz, and Hardjono (2014), the nonnative (Indonesian-English bilingual) pattern of responses was highly similar to that of native GAE listeners in the +3 and -3 dB SNR conditions, but differed at the 0 dB condition. The present study aimed to determine whether or not these results are replicable in a comparable group of non-native bilinguals with a different L1 (Korean). Results revealed that the pattern of responses matched that of Fox et al. (2014) in all conditions; like both Indonesian listeners and monolingual GAE listeners, Korean listeners performed best when target sentences were in SAE at the +3 dB and -3 dB SNR conditions. However, like Indonesian listeners, the Korean listeners demonstrated no benefit from the acoustic features of SAE targets at the 0 dB SNR condition. These findings suggest that bilinguals are consistent in their comprehension of target sentences in masking speech irrespective of their L1 background; unlike at +3 dB and -3 dB conditions, at 0 dB SNR, nonnative listeners exhibit a decreased ability to attend to phonetic details of regional dialects. 2018-12-19 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1531861417828363 http://rave.ohiolink.edu/etdc/view?acc_num=osu1531861417828363 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
