The Lombard advantage (keyword score for Lombard speech minus keyword score for normal speech) in percentage points as a function of SNR and inducer noise level. The rightmost data points indicate native Lombard advantages in the −9 dB condition, taken from Lu and Cooke (2008). Absolute keyword scores for normal speech are 93.5% (quiet), 81.5% (0 dB), 62.0% (−5 dB), and 36.2% (−9 dB). Error bars here and elsewhere indicate standard errors.

Log magnitude spectra for the speech-shaped noise maskers used in experiments I and II. In each case, spectra were calculated using a 50-pole linear predictor fit to a 30 s segment of noise. Differences between the spectra SSN_normal and experiment I are due to the use of different subsets of speech material.

Mean keywords correctly identified by non-native listeners in normal and Lombard speech in speech-shaped noise maskers derived from normal and Lombard speech.

Keyword identification scores for individual talkers in quiet (upper) and combined across the two maskers (lower).
