The frequency pseudocolor-coded speechspectrogram is then obtained by means of a sampling narrow slit placed at Fourier plane in white-light optical spectrum analyzer.
然后在白光光学频谱分析系统中，利用放置在傅里叶频谱面上的取样狭缝得到按频率假彩色编码的频谱图。

Using the invariable characteristics of PCNN time series and entropy series of Spectrogram, people can extract the feature of speakers speech and recognize the speakers rapidly and effectively.
This paper will discuss the role of spectrogram in speech training for the hearing-impaired with special reference to the understanding of cognitive psychology and practical cases.
