本文介绍一种用IBM-PC微型计算机绘制语音信号语谱图的方法,可以作出反映语音动态频谱的语谱图。可以在CRT上显示,也可由打印机打印。语音信号能量的动态范围可达45dB,频率分辨率为F_s/128H_z(F_s为信号取样率)。所有工作由BASIC程序完成。文中附有几张语谱图实例。
This article describes a method for drawing a speech signal spectrogram using an IBM-PC microcomputer to make a speech spectrum that reflects the dynamic spectrum of speech. Can be displayed on the CRT, but also by the printer. The dynamic range of speech signal energy is up to 45dB, the frequency resolution is F_s / 128H_z (F_s is the signal sampling rate). All work is done by BASIC program. The text attached to a few examples of spectrum.
