基于LPCC参数的语音识别系统

摘要

为了识别简单语音,设计了一个基于LPCC参数的语音识别系统。该系统其主要功能有语音信号的录制、播放、预处理、分段滤波、特征提取以及识别语音。最后通过仿真实验验证了本系统能够达到识别简单语音的要求,但仍有需改进的地方,如：能否在复杂环境下识别比较复杂的语音。%In order to recognize simple speech,a speech recognition system based on LPCC parameter is designed,and record,broadcast,pretreat voice signals,subsection filtering,feature extraction and speech recognition are its main functions.This system has achieved discriminate simple voice requirements is verificated by the simulation experiment,but some places are needed to improve,such as：whether complex voice coule be discriminated in complex environment.
