Voice processing device, audio and video output apparatus, communication system, and sound processing method

A voice processing device comprising:

• a sound pickup to receive sounds respectively from a plurality of locations;
• and
• circuitry configured to:
• identify, from the plurality of locations, a sound source location at which a sound source exists;
• and
• enhance a sound from the identified sound source location to output an audio signal including the enhanced sound,
• wherein the circuitry discontinues a process of enhancing a sound from the identified sound source location, in accordance with a frequency of switches of the sound source location between two or more of the plurality of locations.

A method of processing sounds, comprising:

• receiving sounds respectively from a plurality of locations;
• identifying, from the plurality of locations, a sound source location at which a sound source exists, as a current sound source location;
• specifying at least one location of the plurality of locations other than the current sound source location, from at least one sound source location that has been identified as the sound source location during a past predetermined time period, as a specified source location at which a sound to be enhanced exists;
• enhancing a sound from the current sound source location, and a sound from the specified source location;
• and
• outputting an audio signal including the enhanced sounds.
