Conference support device and conference support method

1 . A conference support device that manages a main conference and a plurality of individual conferences to which terminal devices participating in the main conference belong, the conference support device comprising:

at least one processor; and at least one non-transitory memory storing instructions that, when executed by the at least one processor, cause the at least one processor to:

set the main conference and manage connection of the terminal devices participating in the main conference;

associate the plurality of individual conferences with the main conference and manage connection of the terminal devices participating in each of the plurality of individual conferences;

transmit first utterance data to the individual conferences in a case where the first utterance data indicating an utterance content with respect to the main conference has been received from the terminal device;

transmit, in the individual conferences, in a case where the first utterance data has been received, the first utterance data to the terminal devices participating in each of the plurality of individual conferences; and

transmit, in a case where second utterance data indicating an utterance content with respect to one individual conference has been received from one terminal device participating in the one individual conference, the second utterance data to the terminal devices participating in the one individual conference.

2 . The conference support device according to claim 1 , wherein the first utterance data includes terminal identification information for uniquely identifying the plurality of terminal devices, and

wherein the instructions, when executed by the at least one processor, further cause the at least one processor to:

specify the terminal identification information included in the first utterance data; and

transmit the first utterance data and the second utterance data to other of the terminal devices that are other than the terminal device that has transmitted the first utterance data.

3 . The conference support device according to claim 2 , further comprising:

a storage unit configured to store the first utterance data and the second utterance data,

wherein the instructions, when executed by the at least one processor, further cause the at least one processor to:

prohibit, while the first utterance data is being transmitted, transmission and reception between the terminal device transmitting the first utterance data and an individual conference management unit that facilitates management of the connection of the terminal devices participating in each of the plurality of individual conferences;

store, in the storage unit, individual conference data indicating an utterance content made in the individual conference whose transmission and reception is prohibited; and

transmit, after the terminal device that has transmitted the first utterance data finishes utterance in the main conference, the individual conference data to the terminal device that has transmitted the first utterance data in response to a request from the terminal device that has transmitted the first utterance data.

4 . The conference support device according to claim 2 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to:

acquire type information from the terminal device; and

receive the first utterance data when the type information indicates that the utterance content is with respect to the main conference.

5 . The conference support device according to claim 3 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to:

acquire type information from the terminal device; and

receive the first utterance data when the type information indicates that the utterance content is with respect to the main conference.

6 . The conference support device according to claim 1 , wherein the instructions, when executed by the at least one processor, further cause the at least one processor to:

acquire type information from the terminal device; and

receive the first utterance data when the type information indicates that the utterance content is with respect to the main conference.

7 . A conference support method for managing a main conference and a plurality of individual conferences to which terminal devices participating in the main conference belong, the conference support method comprising:

a step of setting the main conference and managing connection of the terminal devices participating in the main conference;

a step of associating the plurality of individual conferences with the main conference and managing connection of the terminal devices participating in each of the plurality of individual conferences;

a step of transmitting first utterance data to the individual conferences in a case where the first utterance data indicating an utterance content with respect to the main conference has been received from the terminal device;

a step of transmitting, in the individual conference, in a case where the first utterance data has been received, the first utterance data to the terminal devices participating in each of the plurality of individual conferences; and

a step of transmitting, in the individual conference, in a case where second utterance data indicating an utterance content with respect to one individual conference has been received from one terminal device participating in the one individual conference, the second utterance data to the terminal devices participating in the one individual conference.
