夹角法 meaning in English

angle offset method
angle-off set
angle-offsetmethod

2 . some theory of high - dimension space is introduced and a new feature extraction method avito correlation - angle is presented based on high - dimension space geometry . 3
介绍了高维空间几何学的一些基本定义，并在此思想上，提出了自相关夹角法对语音信号进行特征提取。
Based on high - dimension space geometry , every speech sample is looked as a point in space . then the speech sample point is extracted feature by lpc , mel - scaled cepstrum analysis or auto correlation - angle . their feature is looked as a point too
基于高维空间几何的思想，把每个样本点和其特征值看作高维空间中的一个点，用线性预测分析、 mel倒谱分析和自相关夹角法对样本点提取特征，然后用点在空间的投影来判别语音和非语音，根据判别结果来比较三种特征提取方法的优劣。
