    • A method and device for performing audio recognition, including: collecting a first audio document to be recognized; initiating calculation of first characteristic information of the first audio document, including: conducting time-frequency analysis for the first audio document to generate a first preset number of phase channels; and extracting at least one peak value characteristic point from each phase channel of the first preset number of phrase channels, where the at least one peak value characteristic point of each phase channel constitutes the peak value characteristic point sequence of said each phase channel; and obtaining a recognition result for the first audio document, wherein the recognition result is identified based on the first characteristic information, and wherein the first characteristic information is calculated based on the respective peak value characteristic point sequences of the preset number of phase channels.
    • 一种用于执行音频识别的方法和装置,包括:收集要识别的第一音频文档; 开始计算第一音频文档的第一特征信息,包括:对第一音频文档进行时间 - 频率分析以产生第一预设数量的相位通道; 以及从所述第一预设数量的短语通道的每个相位通道提取至少一个峰值特征点,其中每个相位通道的至少一个峰值特征点构成所述每个相位通道的峰值特征点序列; 并且获得第一音频文档的识别结果,其中基于第一特征信息识别识别结果,并且其中基于预设数量的相位通道的相应峰值特征点序列来计算第一特征信息。
