Abstract
The invention relates to a voice operating control device and a voice operating control method for identifying the identity of a command issuing person by using an acoustic fingerprint and belongs to the technical field of identify identification. The voice operating control device and the method solve the problem that as the traditional system for identification and control by adopting voice commands can not identify whether operating personnel issuing the commands has operating authorization, the safety loophole of controlling the system is caused. The voice operating control device comprises a scene voice identifying part, a voice fingerprint identification part, a command content analyzing part, an execution processing part, a log processing part and an external output control interface. The voice operating control method is characterized by comprising the steps of judging the identity of the command issuing person by identifying the acoustic fingerprint of the voice commands, and then judging according to the limits of authority to which the identify corresponds whether the voice command issued by the command issuing person is carried out, thereby realizing the matching of different limits of authority with the different voice command operating personnel. The voice operating control device and the voice operating control method are suitable for identifying the identity of the command issuing person in voice command identification and control.
Description
technical field [0001] The invention relates to a voice operation control device and method for identifying a sender's identity by using acoustic fingerprints, and belongs to the technical field of identity identification. Background technique [0002] At present, many control centers, household appliances, and vehicle-mounted systems have begun to use voice command recognition control methods. Since the command authority of the operator is not considered, the system will perform the same operation when anyone issues the same command. This will cause a security risk to the controlled system. Contents of the invention [0003] The present invention aims to solve the problem that the existing system that adopts voice command recognition control does not recognize whether the operator who issued the command has operation authority, which will cause potential safety hazards for the controlled system, and provides a method that uses acoustic fingerprints to identify the identit...
