Abstract

The invention discloses a voice electronic lock. The voice electronic lock adopts an SPCE061A singlechip microcomputer and comprises the following parts: (1) a voice signal acquisition part: a microphone amplifier and a single channel with an AGC (Automatic Gain Control) function are arranged inside the Sunplus singlechip microcomputer SPCE061A for voice signal acquisition; a multiplexed expansion FLASH storage part for storing characteristic parameters of a speaker is also arranged; (2) a loudspeaker output part: a dual-channel 10-bit digital / analog converter with an audio output function, which is inherently arranged in the Sunplus singlechip microcomputer SPCE061A, is utilized to complete various voice playing prompts through various operations during training and recognition by users; (3) a control output part: the corresponding actions can be controlled through a programmable control input / output port of the SPCE061A. The voice electronic lock has good stability and recognizability and good effect and is worthy of promotion and application.

Description

technical field [0001] The invention relates to voice recognition, in particular to a voice electronic lock. Background technique [0002] Biometric identification technology is a technology for identification based on human biological characteristics. It is recognized as the safest, fastest and most convenient identification technology in the current price segment, because each of us has unique and unique biological characteristics from others. Unchanging stability within a certain period of time makes it difficult to impersonate and counterfeit, so using biometric technology for identification is not only accurate, reliable, but also safe. In the field of biometrics, voiceprint recognition, also known as speaker recognition, is loved by people for its unique accuracy, reliability, economy, convenience and safety. Step by step, this safe identification method has occupied an irreplaceable position in people's work and life. [0003] In daily life, locks are widely used, a...
