The circular AMDF is hired to detect pitch period,and the system identify speaker gender correctly and effectively by DSP/BIOS programming as to satisfy realtime processing requirements.
系统采用循环平均幅度差函数(CAM DF)检测基音周期,能够快速、有效的判别说话人的性别。
By fixing the maximum values of tensile stress in all tests but changing the minimum values of tensile stress in various tests, the effect of cyclic stress amplitude or mean stress and their interaction on the damage of materials may be differentiated.
通过固定所有实验中最大拉伸应力值，而改变不同实验中最小拉伸应力值的方法，可区分循环应力幅或平均应力及其交互作用对材料损伤的影响。
