Environmental noise is a stress which induces the Lombard style of speech. The effects of this change in speech style is observed on three automatic speech recognition systems. A low complexity word recognizer using reliably found regions of high phoneme similarity was found to perform as well, under normal and Lombard speech styles, as an HMM-based recog- nizer using cepstral coefficients and their derivatives.
