Abstract :
We present a method to improve the recognition performance under stressful talking conditions. This method is based on preprocessing the speech signals produced under stressful talking conditions when the optimum value of number of poles of the vocal tract transfer function has been determined. Our results show that the optimum value of number of poles under stressful talking conditions is equal to 14. This optimum value improves the recognition rate to a good extent
