Database access authentication device based on voice query

Abstract

A database access authentication device based on voice query comprises a signal receiving device, a sound wave signal amplifying device, a signal oscillating device, a signal harmonic wave modulating device, a voltage stabilizing device, a waveform adjusting device, a signal conversion adjusting device, a signal transmission device and a signal recognition and display device, wherein because the signal receiving device is used for receiving and inputting language signals and performing preliminary storage on the language signals, subsequent further analysis and detection are performed; then, the sound wave signal amplifying device is adopted for amplifying the input language signals, and therefore the signal processing power of the device is increased; then, the signal oscillating device is used for high-frequency oscillation on the signals, and therefore interference of transmitted signals on received signals is reduced; finally a coupler, a circulator and a duplexer of the signal harmonic wave modulating device are used for separating carrier signals from reflecting signals, and transmission signals can be isolated; the waveform adjusting device is adopted for waveform oscillation adjustment and carrier frequency limitation of the transmission signals, and segment processing on signals is achieved.

Description

technical field [0001] The invention relates to the technical field of voice query devices, in particular to a database access authentication device based on voice query. Background technique [0002] Database access voice query technology is mainly based on the recognition system, through the comparison and analysis of individual characteristics that will not be confused, including fingerprint analysis, fingerprint analysis, voice analysis and fundus retina analysis in the traditional sense; the voice analysis is mainly Based on the matching recognition and detection recognition of sound wave symbols, the matching recognition technology mainly processes the voice sound wave into a characteristic data stream, and then compares it with the existing feature model in the system, and finally outputs the detection and recognition results, and the voice input of Chinese characters The system is a typical voice recognition technology, but at the present stage, its bit error rate is...

[0002] Database access voice query technology is mainly based on the recognition system, through the comparison and analysis of individual characteristics that will not be confused, including fingerprint analysis, fingerprint analysis, voice analysis and fundus retina analysis in the traditional sense; the voice analysis is mainly Based on the matching recognition and detection recognition of sound wave symbols, the matching recognition technology mainly processes the voice sound wave into a characteristic data stream, and then compares it with the existing feature model in the system, and finally outputs the detection and recognition results, and the voice input of Chinese characters The system is a typical voice recognition technology, but at the present stage, its bit error rate is very high. The storage of voice calls on GSM mobile phones has certain representative significance, but there is still a long way to go for the accurate calling distance of the phone number. The long distance is mainly because there are still many deficiencies in the existing feature data processing and analysis device, the detection confidence level is not high, and the information processing speed is not fast enough. Therefore, it is necessary to improve the existing database access voice query device. Improve
