摘要

提出了一种提高语音识别性能的方法。该方法是在声道传递函数极点数的最优值确定的情况下，对应激谈话条件下产生的语音信号进行预处理。结果表明，在有压力谈话条件下，最优的极点数为14。该最优值在很大程度上提高了识别率。

Determining the optimum value of number of poles under stressful talking conditions

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.
