【摘要】：當(dāng)前身份識(shí)別系統(tǒng)大多采用密碼識(shí)別技術(shù),容易被竊取或遺失,導(dǎo)致用戶有一定的損失,識(shí)別精度較低.為此,設(shè)計(jì)了一種新的基于web網(wǎng)絡(luò)的身份識(shí)別系統(tǒng),主要由瀏覽器端錄音模塊、聲紋數(shù)據(jù)傳輸模塊和聲紋訓(xùn)練及識(shí)別模塊構(gòu)成.給出系統(tǒng)架構(gòu),依據(jù)系統(tǒng)架構(gòu)在瀏覽器端安裝一個(gè)Activex錄音控件,對(duì)用戶的語(yǔ)音進(jìn)行錄制.通過(guò)預(yù)加重、端點(diǎn)檢測(cè)等方式對(duì)聲紋信號(hào)進(jìn)行預(yù)處理.對(duì)聲紋信號(hào)進(jìn)行特征值提取,通過(guò)信號(hào)轉(zhuǎn)換過(guò)濾信號(hào)中沒(méi)有用的部分,提取出能夠體現(xiàn)用戶錄制語(yǔ)音本質(zhì)屬性的特征參量,依據(jù)提取特征值得到D值,通過(guò)D值實(shí)現(xiàn)身份識(shí)別.實(shí)驗(yàn)結(jié)果表明,所設(shè)計(jì)系統(tǒng)有很高的識(shí)別精度.
[Abstract]:Most of the current identity recognition systems use cryptographic identification technology, which is easy to be stolen or lost, resulting in a certain loss of users and low recognition accuracy. Therefore, a new identification system based on web network is designed. It is mainly composed of browser end recording module, voiceprint data transmission module and voice pattern training and recognition module. The system structure is given. According to the system architecture, a Activex recording control is installed on the browser end. Record the voice of the user. Preprocess the voiceprint signal by pre-weighting and endpoint detection. Extract the eigenvalue of the voiceprint signal and filter the useless part of the signal by signal conversion. The characteristic parameters which can reflect the essential attribute of the speech recorded by the user are extracted and the D value is obtained according to the extracted characteristic value. The experimental results show that the system designed has a high recognition accuracy.
