摘要
语谱图能为语音研究工作者提供丰富的有关语音频谱及时间特性信息,多年来一直是语音研究领域中的重要工具。本文介绍一个由通用微机构成的语音分析系统,它采用改进的FRFT算法提高了运算速度;引入计算机图形学、数字图像处理学等多学科的技术进行二次数据处理,为语音分析探索了一条新路;普通打印机伪中间灰度语图成图提供了一定质量的黑白语图输出。
The spectrogram can provide a lot of information about the speech specstrum and the time's character. An important method in the feild of speech research is it for many years. The paper introduces a kind of speech analysis system consisted of current microcomputer, which uses the improved FRFT(Fast Running Fourier Tranforn) algorithms to increase the computation speed. It makestwo times date processing by introducing computer graphics, digital graph proceesing and so on, puts a new way for the speech analysis and provides the output of black/white spectrograms of good quality for the fale medium gray spectrogram of general typerwriters.
