1. An audio device comprising:
a sound sensor portion;
a sound separation portion;
a sound determination portion;
a processing portion; and
an output portion,
wherein the audio device is an earphone or a headphone,
wherein the sound sensor portion is configured to sense first sound,
wherein the sound determination portion is configured to store a feature quantity of a voice of a user,
wherein the sound determination portion is configured to determine, with a machine learning model, whether the first sound has the stored feature quantity,
wherein the processing portion is configured to analyze an instruction contained in the first sound and, when the feature quantity of the first sound is the stored feature quantity, to generate a signal representing content of the instruction, and, when the feature quantity of the first sound is not the stored feature quantity, to not generate the signal representing content of the instruction,
wherein second sound is sound to cancel noise in the first sound,
wherein third sound is sound electrically input to the audio device,
wherein fourth sound is synthesized sound of the second sound and the third sound,
wherein the processing portion is configured to generate the second sound and the third sound, and
wherein the output portion is configured to output the fourth sound.
