代码说明:

  本次课程设计主要介绍了语音信号的录制、语音信号的采集与分析、语音信号的采样、语音信号的频谱分析、加噪后的频谱分析、滤波器的设计以及对于语音信号的回放等知识。通过 Cool Edit录制一段语音信号,运用MATLAB对其进行时域与频域分析,然后设计滤波器加入噪声进行滤波处理,比较滤波前后始于波形或频谱的变化,最后实现对于语音的回放设计。(Digital voice processing filter design)

    科大讯飞语音转文字源码是一个基于科大讯飞的语音转文字的例子源码,小编测试一下表示被着准确率惊呆了,之前小编用过其他的语音搜索类的工具,但是准确率总是不那么满意,用这个例子我试着读了杂志上的一段话,语速还略微快了一些,但是转换出来的文字只有两个字跟原文不一样,但是还是同音字。(IFLYTEK speech text source is a turn based on iFLYTEK speech text examples of the source code, test bit representation of the being accurate rate was shocked, before Xiaobian used other voice search tool, but the accuracy is always not so satisfactory, for this example I try to read a passage in the magazine, speed is slightly faster, but convert text only two words with the original text is not the same, but still homophones.)

    这 里主要对LMS算法及一些改进的LMS算法(NLMS算法、变步长LMS算法、变换域LMS算法)之间的不同点进行了比较,在传统的LMS算法的基础上发 展了LMS算法的应用。另一方面又从RLS算法的分析中对其与LMS算法的不同特性进行了比较。(Here mainly on the LMS algorithm and some improvements of the LMS algorithm (NLMS algorithm, variable step size LMS algorithm, transform domain LMS algorithm) between the different points of comparison, in the traditional LMS algorithm developed on the basis of the application of the LMS algorithm. On the other hand from the analysis of RLS algorithm and LMS algorithm for its different characteristics compared.)
