本文利用大规模集成电路一开关电容滤波器SCF作为语音特征提取的基本组件,以微机为控制中心,设计了时分复用动态语谱分析系统。能实时提取语音信号的三维谱图。从而提出了一种新的语音信号特征提取的方法。为语音识别技术提供了一种较为简单而有效的途径。
In this paper, a large-scale integrated circuit-switched capacitor filter (SCF) is used as the basic component of speech feature extraction and a microcomputer is taken as the control center to design a time-multiplexed dynamic spectral analysis system. Real-time extraction of the three-dimensional spectrum of speech signals. Thus a new method of feature extraction of speech signal is proposed. For speech recognition technology provides a simple and effective way.
