    • Systems, method, and apparatus for processing a speech utterance or audio record that includes receiving one or more feature vectors characterizing the speech utterance or audio record, each feature vector having a plurality of feature elements, each feature element being associated with a spectral representation of a characteristic of one of a plurality of sequential segments of the speech utterance or audio record; and processing the one or more feature vectors in a rank order filter to obtain one or more normalized feature vectors, each normalized feature vector having a plurality of normalized feature elements corresponding to the plurality of feature elements.
    • 用于处理语音发音或音频记录的系统,方法和装置,包括接收表征语音发音或音频记录的一个或多个特征向量,每个特征向量具有多个特征元素,每个特征元素与 语音发音或音频记录的多个连续片段之一的特征; 以及处理秩阶滤波器中的所述一个或多个特征向量以获得一个或多个归一化特征向量,每个归一化特征向量具有对应于所述多个特征元素的多个归一化特征元素。
