Abstract

Purpose

This study discusses the ways in which the presence of background noise may adversely affect bilingual students' ability to repeat speech, specifically, whether the presence of background noise increases lexical, grammatical, omission, and other errors on the AzBio Sentence Test.

Method

Participants consisted of 15 monolingual English (first language) speakers and 41 bilingual (second language [L2]) speakers from Spanish, Portuguese, and Korean language groups, ranging from students who learned English after the age of 4 years to adulthood. Participants completed the AzBio Sentence Test in both quiet and background noise environments. A language analysis was conducted, and errors were classified under categories of lexical, grammatical, omissions, and other.

Results

The results of this study show that L2 speakers made more lexical, grammatical, omissions, and other errors than first language speakers on the AzBio Sentence Test. In background noise, all bilingual language groups made more errors than monolinguals. Portuguese speakers notably made more omissions than other language groups. This study also shows that participants who were introduced to English at a younger age made fewer errors.

Conclusions

In conclusion, our results corroborate previous research, indicating that bilingual speakers have more difficulty accurately interpreting speech in the presence of background noise. These findings have implications for classroom instruction considering the statistically higher percentage of omissions made by L2 speakers.
