研究了心理声学和心理语言学因素对朗伯德语可懂度的影响。当使用加性白色高斯噪声和感知测试时进行的完整的词汇研究，易混淆的词汇（除了子集（m，n））是较难理解时，在噪声中比在安静时产生。这一结果在不同类别的听众中是一致的。使用多说话者噪声作为加性噪声，结果发现，所使用的噪声类型和所获得的可懂度分数之间存在很强的相互作用，并且女性说话者比男性说话者更容易理解。使用音素调整的信噪比，据观察，与声学分析一致，在噪声中产生语音可以降低辅音-元音能量比。讨论了这些结果对鲁棒语音识别器的发展的影响。
The influence of psychoacoustic and psycholinguistic factors on the intelligibility of Lombard speech compared to normal speech production was studied. When using additive white Gaussian noise and when the perceptual tests were performed on the complete vocabulary studied, confusable vocabularies (except the subset (m,n)) were less intelligible when produced in noise than when produced in quiet. This result was consistent among the different classes of listeners studied. Using multitalker noise as additive noise, it was found that there is a strong interaction between the type of noise used and the intelligibility scores obtained, and that female speakers are more intelligible than male speakers. Using a phoneme adjusted signal-to-noise ratio, it was observed, in agreement with acoustic analyses, that producing speech in noise can decrease the consonant-to-vowel energy ratio. The implications of these results for the development of robust speech recognizers are discussed.>
