Abstract
Even though many non-native (L2) speakers produce speech in noisy environments (so-called “Lombard speech”) regularly, the perception of L2 Lombard speech has not been studied yet. We studied how native (L1) and non-native listeners perceive L2 Lombard speech. Fifty-eight English speakers determined whether the same keyword sounded more native-like when produced in noise focus (NF) or in QNonF (quiet non-focus). The keywords were produced by L1 and L2 speakers. The 28 keyword pairs consisted of three categories: words with initial /θ/, Dutch-English cognates with a schwa in American English and a full vowel in Dutch, and words with final voiced obstruents. Linear mixed effects modeling showed that American speakers were perceived to sound more native in QNonF than NF and Dutch speakers showed the opposite pattern, especially in the schwa category. In conclusion, listeners perceive the accentedness of native and non-native Lombard speech differently depending on the keyword category.
