摘要
本文通过对实验结果的分析,研究在噪声情况下采用线性预测方法,对语音特征进行提取并且确定合理的线性预测系数阶数。通过对结果的分析可知:线性预测系数是一种运算速度很快,有一定抗噪能力,识别精度较高的语音识别参数。
In this paper, we get the features and reasonable factor of LPC in noisy environment by the analysis of experimental results. Experimental results show that LPC is a speech recognition parameter which has fast speed, some capacity of resistance to noise and high precision.
