Abstract: A non-transitory computer-readable recording medium having stored therein a program that causes a computer to execute a procedure, the procedure includes detecting a plurality of voice sections from an input sound that includes voices of a plurality of speakers, calculating a feature amount of each of the plurality of voice sections, determining a plurality of emotions, corresponding to the plurality of voice sections respectively, of a speaker of the plurality of speakers for each of the plurality of voice sections, and clustering a plurality of feature amounts, based on a change vector from the feature amount of the voice section determined as a first emotion of the plurality of emotions of the speaker to the feature amount of the voice section determined as a second emotion of the plurality of emotions different from the first emotion.

Abstract: An apparatus receives, via an input device, query input data including a word or a phrase, and acquires search result set data using the query input data. The apparatus acquires, for a value indicating a strength of a relationship between each impression word included in an impression word group and each word included in the query input data, and extracts the first feature word group according to the value indicating the strength of the relationship with each word, from the impression word group. The apparatus displays the search result set data using the first feature word group as an item.

Abstract: A determination method includes: receiving first sensing data that includes either video or voice generated in a first remote call made between a first account and a second account and second sensing data that includes either video or voice generated in a second remote call made between the first account and the second account; referring to a storage unit that stores feature information extracted when a specific situation for a person who corresponds to the first account occurs in the first sensing data in association with the specific situation when occurrence of the specific situation for the person who corresponds to the first account is detected in the second sensing data; and making determination related to spoofing on a basis of a matching state between the feature information for the specific situation in the storage unit and the feature information for the specific situation detected from the second sensing data.
