A speech signal filterbank, using melscale frequency and framebanking.( 1. For speech signal can be represented as a discrete sequence of frames (or feature vectors) that can be used as the input to a speech recogniser. Important ideas and techniques that are used in the assignment are the design of a (Mel frequency scale) audio filterbank, , windowing of a continuous audio signal, spectrum analysis of the signal, filtering as multiplication in the frequency domain, the visual representation of a speech signal as a spectrogram, appreciation of the acoustic variability in real speech utterances. 2. To gain a deeper knowledge of the application of MATLAB programming to audio signal processing. 3. To gain practice in the art of writing a formal report: structure, content, style, use of diagrams, presentation etc. etc. )

该程序用matlab编写数值积分方法，包括梯形公式，Simpson公式和Romberg算法，在main.m文件测试三类算法。这是数值计算方法是必须掌握的代码。(The program is prepared using matlab numerical integration methods, including trapezoidal formula, Simpson and Romberg algorithm for three kinds of formulas in main.m file for testing. Is the numerical calculation method must master code.)
