在对语声进行数字处理的过程中,经常要对分析后的图形数据进行打印,以便进行详细的分析。以往多是采用屏幕硬拷贝的方法一幅幅地输出图形,这在处理较长的语声信号时是极不方便的。因此,我们实现了一种以计算机系统为核心的图形打印系统,可以将语声处理中常用的图形数据连续地打印输出。 In the process of digital processing of speech, it is often necessary to print the analyzed graphic data for detailed analysis. In the past, the use of screen hard copy method to output graphics, which is very inconvenient when dealing with longer voice signals. Therefore, we have implemented a graphic printing system that takes a computer system as the core, and can continuously print and output graphic data commonly used in speech processing.
