在MATLAB中，符号计算虽以数值计算的补充身份出现，但涉及符号计算的指令使用、运算符操作、计算结果可视化、程序编制以及在线帮助系统都是十分完整、便捷的。(In MATLAB, the symbolic computation added that though in the numerical identity of the emergence of the instructions involving the use of symbolic computation, operator operation, results visualization, programming and on-line help system are very complete and convenient.)

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.
