Sound input-output control apparatus, sound input-output control method, and non-transitory computer-readable medium

A sound input-output control method in which a plurality of sound output apparatuses each independently mounted on at least one user to output sound toward the at least one user are controlled by a sound input-output control apparatus, wherein the sound input-output control apparatus:

• determines whether a distance between at least two of the plurality of sound output apparatuses is equal to or longer than a predetermined distance,
• controls each of the sound output apparatuses to perform first operation when having determined that the distance between at least two of the plurality of sound output apparatuses is shorter than the predetermined distance, and
• controls each of the sound output apparatuses to perform second operation when having determined that the distance between at least two of the plurality of sound output apparatuses is equal to or longer than the predetermined distance, wherein:
• at least one of the sound output apparatuses includes a sound input unit configured to collect voice of a user on which the one sound output apparatus is mounted;
• the sound input-output control apparatus controls the one sound output apparatus to output a voice signal in accordance with the voice collected by the sound input unit of the one sound output apparatus to any other sound output apparatus when it is determined that the distance between at least two of the plurality of sound output apparatuses is equal to or longer than the predetermined distance;
• and
• the sound input-output control apparatus controls the other sound output apparatus to receive the voice signal and to output the voice toward the user in accordance with the voice signal.

A non-transitory computer-readable medium that stores a computer program that causes a sound input-output control apparatus to execute processing of controlling a plurality of sound output apparatuses each independently mounted on at least one user to output sound toward the at least one user, the computer program causing the sound input-output control apparatus to execute;

• processing of determining whether a distance between at least two of the plurality of sound output apparatuses is equal to or longer than a predetermined distance;
• and
• processing of controlling each of the sound output apparatuses to perform first operation when having determined that the distance between at least two of the plurality of sound output apparatuses is shorter than the predetermined distance, and controlling each of the sound output apparatuses to perform second operation when having determined that the distance between at least two of the plurality of sound output apparatuses is equal to or longer than the predetermined distance, wherein:
• at least one of the sound output apparatuses includes a sound input unit configured to collect voice of a user on which the one sound output apparatus is mounted;
• the computer program further causes the sound input-output control apparatus to execute:
• processing of controlling the one sound output apparatus to output a voice signal in accordance with the voice collected by the sound input unit of the one sound output apparatus to any other sound output apparatus when it is determined that the distance between at least two of the plurality of sound output apparatuses is equal to or longer than the predetermined distance;
• and
• processing of controlling the other sound output apparatus to receive the voice signal and to output the voice toward the user in accordance with the voice signal.
