Auto reply system, auto reply device, auto reply method, and computer program for auto reply

An auto reply method comprising:

• generating first reply information to an utterance of an occupant of a vehicle by inputting input information including voice information representing the utterance into a first generation model, the first generation model being implemented in the vehicle and pre-trained to generate the first reply information;
• generating inquiry information representing the utterance, based on the input information;
• generating second reply information to the inquiry information by inputting the inquiry information into a second generation model provided outside the vehicle, the second generation model being pre-trained to generate the second reply information and larger than the first generation model;
• and
• replying to the occupant, based on at least one of the first and second reply information.

A non-transitory recording medium that stores a computer program for auto reply, the computer program causing a computer to execute a process comprising:

• generating first reply information to an utterance of an occupant of a vehicle by inputting input information including voice information representing the utterance into a first generation model, the first generation model being implemented in the vehicle and pre-trained to generate the first reply information;
• generating inquiry information representing the utterance, based on the input information;
• generating second reply information to the inquiry information by inputting the inquiry information into a second generation model provided outside the vehicle, the second generation model being pre-trained to generate the second reply information and larger than the first generation model;
• and
• replying to the occupant, based on at least one of the first and second reply information.

An auto reply device comprising:

• a processor configured to:
• generate first reply information to an utterance of an occupant of a vehicle by inputting input information including voice information representing the utterance into a first generation model, the first generation model being implemented in the vehicle and pre-trained to generate the first reply information,
• generate inquiry information representing the utterance, based on the input information,
• transmit the inquiry information to a server provided outside the vehicle via a communication device mounted on the vehicle,
• receive second reply information generated based on the inquiry information from the server;
• and
• reply to the occupant, based on at least one of the first and second reply information.
