| 摘 要： | 语音识别是让机器自动识别和理解语音信号,并把语音信号转变为相应的文本或命令的技术.通过对特定人孤立词语音特点的研究,在对语音信号进行预处理的过程中,选择过零率与短时平均能量两项指标作为对语音信号端点检测的依据,提取语音线性预测系数,通过计算分析后获得线性预测倒谱系数,作为语音特征参数.选择动态时间规整法为模板匹配算法,...

| Abstract: | Voice-identification is a kind of technology that is using computer to transfer the voice signal to an associated text or command by identification and understand.Zero-crossing rate and short-term energy are selected as the basis in the endpoint detecting in preprocessing of speech signal through the studying of the characters of single-word.LPC(Linear Prediction Coefficient)is extracted from the signal,then cepstral coefficient is obtained as the speech characteristic parameters.DTW(Dynamic Time Warping)al... |
