Information processing method, information processing device, and non-transitory computer readable recording medium

An information processing device, comprising:

• a first acquisition part that acquires a face similarity indicating a similarity between a face of a first person and a face of a second person;
• a second acquisition part that acquires a voice similarity indicating a similarity between a voice of the first person and a voice of the second person;
• an integrating part that calculates an integrated similarity by integrating the face similarity and the voice similarity, and determines the integrated similarity as a final similarity when the face similarity falls within an integrated range, and determines the face similarity as a final similarity when the face similarity is out of the integrated range;
• and
• an output part that outputs the final similarity.

A non-transitory computer readable recording medium storing a program, comprising:

• causing a computer to execute:
• acquiring a face similarity indicating a similarity between a face of a first person and a face of a second person;
• acquiring a voice similarity indicating a similarity between a voice of the first person and a voice of the second person;
• calculating an integrated similarity by integrating the face similarity and the voice similarity, and determining the integrated similarity as a final similarity when the face similarity falls within an integrated range, and calculating the face similarity as a final similarity when the face similarity is out of the integrated range;
• and
• outputting the final similarity.
