Device control method, device management system, and voice input apparatus

A method in a device management system connected to a plurality of target devices for managing the plurality of target devices, the plurality of target devices being arranged in a same household, the method comprising:

• receiving, from a remote controller associated with a first target device among the plurality of target devices, identification information that identifies the remote controller;
• specifying the first target device by referencing a first database in which the identification information and a device ID of the first target device are associated;
• receiving, from a voice input apparatus connected to the device management system, instruction information that includes first voice information indicating an operation instruction for any target device among the plurality of target devices;
• recognizing the operation instruction from the first voice information included in the received instruction information;
• determining whether or not second voice information indicating a second target device among the plurality of target devices is included in the instruction information, and,
• transmitting, (i) when the second voice information is not included in the instruction information, a control command for executing the recognized operation instruction to the first target device, the first target device corresponding to the remote controller is specified based on the received identification information, and (ii) when the second voice information is included in the instruction information, the control command to the second target device.

A device management system that is connected to a plurality of target devices arranged in the same household and that manages the plurality of target devices, comprising:

• a device management apparatus;
• and
• a voice input apparatus,
• wherein the device management apparatus which, in operation,
• receives, from the voice input apparatus associated with a first target device among the plurality of target devices, instruction information that includes first voice information indicating an operation instruction for any target device among the plurality of target devices;
• recognizes the operation instruction from the first voice information included in the received instruction information;
• specifies the first target device by referencing a first database in which the identification information and a device ID of the first target device are associated;
• determines whether or not second voice information indicating a second target device among the plurality of target devices is included in the instruction information;
• and
• transmits, (i) when the second voice information is not included in the instruction information, a control command for executing the recognized operation instruction to the first target device, and (ii) when the second voice information is included in the instruction information, the control command to the second target device, and
• the voice input apparatus which, in operation transmits the instruction information to the device management apparatus.
