数字语音是信号的一种，我们处理数字语音信号，也就是对一种信号的处理，那信号是什么呢？ 信号是传递信息的函数。离散时间信号——序列——可以用图形来表示。 按信号特点的不同，信号可表示成一个或几个独立变量的函数。例如，图像信号就是空间位置（二元变量）的亮度函数。一维变量可以是时间，也可以是其他参量，习惯上将其看成时间。 (Digital Voice is a signal that we deal with digital voice signal, that is, the processing of a signal, that signal what is it? Signal is a function of transmitting information. Discrete-time signal- sequence- can be used to indicate the graphics. According to the different signal characteristics, signal or can be expressed as a function of several independent variables. For example, the image signal is the spatial location (binary variables) of the brightness function. Variables can be one-dimensional time and other parameters can be, habits will be time to treat it as a.)

可以对信号进行短时傅里叶变换，也可以对反射系数序列进行短时傅里叶变换(STFT)
