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。
Phonograms provide voice researchers with a wealth of information about the frequency spectrum and temporal characteristics of speech and have been an important tool in the field of speech research for many years. In this paper, we introduce a speech analysis system composed of a universal microcomputer, which uses an improved FRFT algorithm to improve the speed of computing. The introduction of computer graphics, digital image processing and other multidisciplinary techniques for secondary data processing, to explore a new voice analysis Road; ordinary printer pseudo-intermediate grayscale map to provide a certain quality black and white language map output.
