【摘要】 设计了一套基于LabVIEW的语音身份认证系统,以LabVIEW2009为开发平台,采用改进的美尔倒频谱系数法进行语音信号特征提取,采用矢量量化模型进行语音识别,实现了与文本、性别无关的声纹识别。实验结果表明该系统能够有效克服环境噪声、说话人声音变异带来的影响。更多还原

【Abstract】 This paper presents a voiceprint recognition system based on LabVIEW,applying the improved MEL cepstrum coefficient for voice signal feature extraction on the platform of the LabVIEW2009.This method uses vector quantization model for voice recognition to realize a voiceprint recognition system which is not related to speech text and speaker’s gender.The experimental result shows that this system is capable of effectively overcoming the impact produced by environmental noise and the variation of the speaker’s voice.更多还原
