The intelligent lock can be reasonably and scientifically controlled to realize restrictive setting menu opening in different time periods according to the setting of an administrator; the safety of the intelligent lock is greatly improved. After the voiceprint validity and the voiceprint setting authority are verified, the user is proved to have the setting authority, namely, the voiceprints of the user for the first time and the second time are input into a user voiceprint library, so that the voiceprint verification and comparison can be successfully completed by the fact that the user sends the same type of opening audio frequency next time, the success rate of voiceprint verification and comparison is greatly improved, and the interference caused by the voiceprints due to the influence of illness or diet of the user can be further eliminated.
The audio processing process in the step c comprises: voice compression, real-time automatic detection of voice passwords, pre-emphasis, windowing, framing, denoising and audio parameter feature extraction. The audio processing is carried out before the voiceprint comparison judgment, so that the success rate of voiceprint subsequent finite judgment comparison can be greatly improved.
And a step a of storing the established user voiceprint library on a cloud server. The user can open the door by using the voiceprint at a short distance and can also remotely use the talkback mode to set the door lock by using the voiceprint.
