概要
As it becomes increasingly common to encounter English speakers with diverse speech varieties, second language listening assessments that only assess one speech variety of English have become less defensible. However, using speakers with diverse speech varieties may threaten test fairness because test takers’ listening could be affected by familiarity with a particular speech variety. In an attempt to find a solution to this problem, a two stage study was carried out. In stage 1, an instrument was developed that could be used to measure a speaker’s strength of accent, and in stage 2, an attempt was made to use the instrument to select speakers with speech varieties that were fair for all listeners. In Stage 1 of the study, a Many-Facet Rasch Measurement analysis, which included 20 English speakers and 100 English listeners, was used to indicate the reliability of a strength of accent scale and how it was used by native and non-native users of English. In Stage 2 of the study, the strength of accent scale was used to select nine speakers for a large-scale (N = 21,726) study. ANOVA was used to identify a threshold accent strength that could be used to guide selection of listening assessment speakers for a high stakes language assessment (TOEFL iBT).
