Analysis of speech production in a noisy environment

This study aims to identify the compensatory strategies that speaker develops in speech production in noisy environment. We have developed a method which allows studying the effect of noise on acoustic parameters that characterize the speech signal (F0 duration, formants, cepstral and LPC parameters). The results reflect the speakers´ attitudes towards noise and allowed a classification of acoustic parameters used in order of the sensitivity to noise. These results can then be decisive in the choice of acoustic parameters in communication systems.
