    目前2.4kbps的混合激励线性预测 (MELP) 语音编码方法已经被确定为美国新的联邦语音编码标准.本文提出了一种改进的MELP语音编码方法,利用滤波器相似度和基于LPC系数分类的矢量量化技术,可以把MELP的码率降到1.7kbps以下,仍有较好的合成语音质量.(An Improved MELP Speech Coder)

    (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)

    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).)
