Abstract—Several algorithms have been developed for tracking
formant frequency trajectories of speech signals, however most of
these algorithms are either not robust in real-life noise environments
or are not suitable for real-time implementation. The algorithm
presented in this paper obtains formant frequency estimates
voiced segments of continuous speech by using a time-varying
adaptive filterbank to track individual formant frequencies. The
formant tracker incorporates an adaptive voicing detector and a
gender detector for formant extraction continuous speech,
for both male and female speakers. The algorithm has a low signal
delay and provides smooth and accurate estimates for the first four
formant frequencies at moderate and high signal-to-noise ratios.
Thorough testing of the algorithm has shown that it is robust over
a wide range of signal-to-noise ratios for various types of background
noises.

通过计算短时信号熵，与阈值比较，得到判决结果。并采用顺序统计滤波器（最大值滤波器）对所得熵值滤波，提高判决精度。
能有效的分辨出语音信号和噪声信号，且通过后端平滑处理，使语音检测结果更加集中。(VAD based on short-time entropy, precision improved by using order-statistical-filter, VAD result is smoothed to make the result more accurate.)
