关于端点检测的几种方法，语音样本是自己录制的，对传统算法做了一些改进，加入了去噪，去噪之后再进行端点检测，均调通 vad0303：自己设置调整门限为一定值 vad0310：根据能量值和过零率设置门限，自适应门限值 vad0310_2：基于比例因子的门限自调整 vad0310.m加入了噪声，端点检测前都噪声进行了处理 entropy.m：基于自适应子带频谱熵的稳健性语音端点检测 可用于语音增强及端点检测 dbdoor.m：双门限算法，用于语音端点检测。可以通过调整门限值，并加入门限自适应算法，实现语音端点检测(Several methods on endpoint detection, recording their own voice samples, the traditional algorithm has made some improvements, adding a de-noising, and then after de-noising endpoint detection are transferred through)

改程序为切比雪夫拓扑结构的直线阵的matlab代码(Reform program for the Chebyshev linear array topology matlab code)

1）已知2N点实数序列 N=64。用一个64点的复数FFT程序，一次算出 ，并绘出频谱 。 （2）已知某序列 在单位圆上的N=64等分样点的Z变换 。用N点IFFT程序计算 ，绘出图像 。 (1) known 2N-point sequence of real numbers N = 64. With a 64-point complex FFT process, a calculated and mapped the spectrum. (2) known to a certain sequence in the unit circle on the N = 64 sub-samples of the Z transform. N-point IFFT procedures used, the mapped image.)
