摘要
介绍在通用PC机上实现语音三维语谱绘图软件的设计方法。根据线性预测分析技术,采用两种出图方式,通过软件编程将提取的频谱包络在显示器和打印机上绘制成图。其绘图功能及效果可与绘图仪相比拟,具有方便灵活的特点。
A programming design which can be used for drawing speech 3-D spectrogram on PC computer is introduced. Based on linear prediction analysis, speech spectrum contours can be extracted and drawed out in different ways, such as on displayer and printer. This method has similar effects as by spectrograph. It is easy and flexible to operate or control.
