Levi, S. V., Winter, S. J., and Pisoni, D. B. (2007). Speaker-independent factors affecting the perception of foreign accent in a second language. Journal of the Acoustical Society of America, 121(4), 2327-2338.

Summary: Angela
The study of speaker-dependent factors has been the mainstream of foreign accent perception research. However, speaker-independent factors have also been shown to have an effect on foreign accent perception. In this study, the authors focused on the two speaker-independent factors: listening context, which was further divided into the auditory-only group and the auditory plus orthography group, and lexical frequency. The result for lexical frequency was compatible with the authors’ prediction. When words had higher frequency, they tended to be rated as less accented. However, the result for listening context was harder to interpret. In general, when auditory stimuli alone was presented, both native and non-native speakers were rated lower comparing with the group where both auditory and orthography was presented. Taking the two factors together, it can be seen that while the presence of auditory and orthography information reduced the influences of lexical frequency, it increased the perceived differences between native and non-native speakers.
