摘要
生物识别技术是利用人体生物特征进行身份认证的一种技术，是目前公认的最为方便与安全的识别技术。由于每个人的生物特征具有与其他人不同的唯一和在一定时期内不变的稳定性，不易伪造和假冒，所以利用牲识别和技术进行身份认证，安全、准确、可靠。 本设计介绍采用声纹识别技术、在凌阳SPCE061A单片机上实现的一种语音电子门锁身份认证系统。实验结果表明，系统性能稳定，识别效果好，可以推广使用。关键词:声纹识别 基于周期 线性预测 模式匹配 DTW
Abstract: The biological recognition technology is carries on the status authentication using the human body biological features one kind of technology, is the present recognition most convenient and the safe recognition technology. Because each person's biological features have with other people different only and withing certain amount of time the invariable stability, not easy forge and counterfeit, therefore carries on the status authentication using the domestic animal recognition and the technology, the security, is accurate, is reliable. This design introduction uses the voice print recognition technology, one kind of pronunciation electronic lock status authentication system which monolithic integrated circuit realizes in Ling Yang on the SPCE061A. The experimental result indicated that the system performance is stable, the recognition effect is good, may promote the use.
Key word: Voice print recognition based on cycle linear prediction pattern matching DTW
