Autonomous mobile body, information processing method, and information processing apparatus

A non-transitory computer readable medium having stored thereon computer-executable instructions, which when executed by a computer, cause the computer to execute operations, the operations comprising:

• concurrently recognizing a plurality of motions of an autonomous mobile body, wherein
• each motion of the plurality of motions is associated with a corresponding operation sound of a plurality of operation sounds,
• the plurality of operation sounds acoustically expresses physical motions of the autonomous mobile body,
• the physical motions correspond to the plurality of motions, and
• each operation sound of the plurality of operation sounds has a respective priority;
• determining a first operation sound of the plurality of operation sounds, wherein
• the first operation sound has a highest priority among the plurality of operation sounds, and
• the first operation sound is associated with a first motion of the plurality of motions;
• changing a parameter of the first operation sound to reflect a second motion of the plurality of motions, wherein
• the second motion is associated with a second operation sound of the plurality of operation sounds, and
• the second operation sound has a lower priority than the first operation sound;
• and
• controlling an output of an output sound, wherein the output sound includes the first operation sound having the changed parameter.

An information processing apparatus, comprising:

• a central processing unit (CPU) configured to:
• concurrently recognize a plurality of motions of an autonomous mobile body, wherein
• each motion of the plurality of motions is associated with a corresponding operation sound of a plurality of operation sounds,
• the plurality of operation sounds acoustically expresses physical motions of the autonomous mobile body,
• the physical motions correspond to the plurality of motions, and
• each operation sound of the plurality of operation sounds has a respective priority;
• determine a first operation sound of the plurality of operation sounds, wherein
• the first operation sound has a highest priority among the plurality of operation sounds, and
• the first operation sound is associated with a first motion of the plurality of motions;
• change a parameter of the first operation sound to reflect a second motion of the plurality of motions, wherein
• the second motion is associated with a second operation sound of the plurality of operation sounds, and
• the second operation sound has a lower priority than the first operation sound;
• and
• control an output of an output sound, wherein the output sound includes the first operation sound that has the changed parameter.
