鉴于人眼对彩色的分辨率远远高于灰度差分辨率的特点,提出了一种利用C#程序实现伪彩色显示的新方法,该方法通过非线性映射变换函数,建立频谱幅度与颜色的对应关系,从而实现伪彩色显示,并将其用于语谱图显示及语音信号处理界面设计中;此外,还将语音播放功能加入语谱图显示过程中,实现了"可视"语言的播放.该方法编程简单,界面设计灵活,对设备的要求较低,在普通PC机上即可实现.
鑒于人眼對綵色的分辨率遠遠高于灰度差分辨率的特點,提齣瞭一種利用C#程序實現偽綵色顯示的新方法,該方法通過非線性映射變換函數,建立頻譜幅度與顏色的對應關繫,從而實現偽綵色顯示,併將其用于語譜圖顯示及語音信號處理界麵設計中;此外,還將語音播放功能加入語譜圖顯示過程中,實現瞭"可視"語言的播放.該方法編程簡單,界麵設計靈活,對設備的要求較低,在普通PC機上即可實現.

Concerning that the human eye to color resolution is much higher than gray-scale difference,this paper proposed a new method to show the spectrogram by C# procedure,which focused on the mapping transformation function and built up the relationship between spectral magnitude and color,to make pseudo-color display come true,and also used it for speech spectrogram display and audio signal processing interface design. Meanwhile in order to achieve better analysis and learning effects,the authors added audio play function so as to watch the spectrogram while listening to the corresponding audio. This method,with simple programming,flexible interface design and less demand on the equipment,can be realized on ordinary PC.
