| 摘 要： | 根据AMR语音编码算法的特点，研究了AMR语音编码对男声和女声参数特性的差异。在处理分析了大量男声和女声语音数据的基础上，对AMR语音编码中线谱频率(LSF)参数和基音周期参数进行提取和统计，主要研究了这2个参数在样本均值和样本方差方面对男声和女声的差异，并给出了相应的结论和性能优化建议。

| Abstract: | According to the trait of AMR speech coding algorithm,the parameter characteristic difference between male and female for AMR speech coding is studied in this paper.Based on the analysis of a lot of male and fe-male speech data,we take out the statistical parameters of LSF and Pitch for AMR speech coding and studied the differences between the mean values and between the deviations,and then,we draw a corresponding conclusion and give the improvement advice for AMR speech coding. |
