摘要
声音识别技术作为语言信号处理技术的重要分支,有着非常大的应用前景。论文主要是基于Lab VIEW实现声音在线的检测和特征信息的提取以及识别声音来源的设计。利用笔记本电脑中自带声卡,采用Lab VIEW中带的子VI调用来驱动电脑声卡对麦克风录入的声音进行检测、滤波、频谱分析、特征值提取、保存以及最后对不同声音进行对比,最终确定声音信息与发音人是否匹配。
Voice recognition technology is an important branch of language signal processing technology,with very large application prospect.This artical mainly realizes the detection of voice online and the extraction of feature information and the design of the sound source based on Lab VIEW.Using the built-in sound card in the notebook computer,using Lab VIEW in the subvi call to drive the computer sound card to test the microphone input voice,filtering,spectrum analysis,eigenvalue extraction,storage,and finally compares with different sound final voice information match with pronunciation.
