Speeching
端点检测算法采用现阶段比较精确的时频方差检测法,模式识别和模板匹配采用的是改进后的DTW算法(主要是限定了DTW的搜索路径,进一步精确了DTW的平行四边形的形状,进一步的减少匹配中的参数存贮量以及多余的搜索路径)。(Endpoint detection algorithm uses more precise at this stage variance time-frequency detection, pattern recognition and template matching is based on the improved DTW algorithm (DTW is mainly limited to the search path, and further precision of the DTW parallelogram shape, and further reduction of matching the parameters in the storage volume as well as the extra search path).)

VoiceToWord_yysb
简单语音识别源码是一个调用讯飞语音识别SDK的例子源码是一个最纯净的Demo比较容易看懂。实现的是点击按钮开始语音监听,手机需要联网,2/3G的均可,识别后会以Toast的方式提示出来,识别率还是比较高的。之前自己是用别人的Demo总是不成功,是因为,讯飞的SDK想使用是需要APPID的,可能过太长时间久会注销,还有,未通过审核的APPID每天只能试用500次,如果太多人试用,就是达到上限导致无法使用。(A simple speech recognition source code is a call Ifly speech recognition SDK example source code is a demo of the purest easier to understand. The realization of the click button to start the voice listening, mobile phone need to networking, 2/3G can, after the recognition will be prompted by Toast way out, the recognition rate is still relatively high. Before he is with someone else s demo is not always successful, is because the Xunfei SDK to use is appid, may be too long for a long time will be canceled, and not through the audit appid every day can only be tried out 500 times, if too many people tried is reaching the limit to use.)

The-FIR-filter-design
(附带有文档,文档中有方案,有程序有结果,设计完后对一段语音进行处理)给定滤波器的规一化性能指标(参考指标,实际中依据每个同学所叠加噪声情况而定)通带截止频率wp=0.25*pi。 采用窗函数法设计低通、高通、带通型FIR滤波器,对叠加噪声前后的语音信号进行滤波处理,绘出滤波器的频域响应,绘出滤波后信号的时域波形和频谱,并对滤波前后的信号进行对比,分析信号的变化;在相同的性能指标下比较各方法的滤波效果,并从理论上进行分析((With the document, document, program, program results, the design after a voice) to set the filter rules of performance indicators (reference, practice, each student adding noise may be) passband cutoff frequency wp = 0.25* pi. Window function method to design low pass, high pass, band-pass FIR filter, filtering the voice signal before and after adding noise, draw the filter frequency response plot the time-domain waveform and spectrum of the filtered signal, and filtering the signal before and after comparison and analysis of signal changes the filtering effect of the various methods in the same performance indicators, and the theoretical analysis)
