摘要
生物識別技術是利用人體生物特征進行身份認證的一種技術,是目前公認的最為方便與安全的識別技術。由于每個人的生物特征具有與其他人不同的唯一和在一定時期內不變的穩定性,不易偽造和假冒,所以利用牲識別和技術進行身份認證,安全、準確、可靠。 本設計介紹采用聲紋識別技術、在凌陽SPCE061A單片機上實現的一種語音電子門鎖身份認證系統。實驗結果表明,系統性能穩定,識別效果好,可以推廣使用。關鍵詞:聲紋識別 基于周期 線性預測 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
