语谱图是对一段语音在频域各个频段的能量的一种显示方式，一般做法是把语音分成若干帧，加窗后作FFT，求出每一帧不同频率的能量，求出语音每一帧不同频率的能量，一般是不同能量显示成不同颜色，显示成所谓语谱图。-The spectrogram display period of a voice in the energy band of the frequency domain, the general practice is the voice to be divided into several fr a mes, plus window made after FFT, calculate the energy of each fr a me at different frequencies, find the voice of each the energy of the fr a me at different frequencies, different energy displayed as different colors, showing a so-called spectrogram.
