[0057] If the master answers content such as "Ignore the temporary situation" or "Don't care about it", then the image is not pre-saved, and other answer content instructions are classified and stored in the corresponding instruction categories.

[0058] Specific operation example 2:

[0059] Application of the robot voice control system in remote monitoring

[0060] In the first-level voice setting interface of the voice control APP 11, if there is a monitoring driving interface, click "Voice recording on / off" in the voice intercom interface to "on", then the whole process of the robot driving the vehicle from point A to point B can be remotely monitored. When an abnormality occurs during the transportation process, the user can talk to the robot through the microphone of the intelligent mobile terminal 1 installed with the voice control APP 11, and the call information can realize remote conversation through the voice recognition control main board 7. The content can also be transmitted to the voice recognition control main board 7 through the multi-protocol gateway 6 for recognition, then processed by the audio processing and power amplifier module 4, and played by the speaker 5 to answer the questions of the remote monitoring personnel. For example, the robot plays through the speaker 5 and asks the operator at point B in the distance: "When will it be loaded onto the vehicle?" When the operator at point B replies: "It will be completed in 1 hour", the voice content is transmitted back to the remote mobile terminal from the microphone 2 at the robot's ear, and the monitoring personnel can hear the reply of the operator at point B through the communication network between the voice recognition control main board 7 and the multi-protocol wireless transmission and reception module 3.
