Description

technical field [0001] The present invention relates to the field of electronics, in particular to the field of digital signal processing, and in particular to voice recognition technology, in particular to a voiceprint recognition and unlocking module and a recognition and unlocking method for a building intercom outdoor machine. Background technique [0002] In the prior art, building intercom products are widely used. There are four unlocking methods for the outdoor station in the building intercom equipment: key unlocking, password unlocking, card unlocking, and biometric unlocking. Among them, card unlocking is the most widely used. However, the traditional key is easy to be lost and copied without authorization; the password is easy to be stolen; Scratches, sticky dust, improper placement of fingers, etc. are likely to cause rejection, and the contact between the fingerprint and the identification device makes this method not hygienic enough, and it is easy to make pe...
