Abstract: An information processing system includes one or plural processors configured to acquire a speech image including a speaking person, acquire display information for displaying spoken content of the speaking person, and perform a control of displaying the display information in a specific region not overlapping with a face of the speaking person in the speech image.

Abstract: An information processing system includes a processor configured to acquire operation information of an operation device that is configured such that each of plural candidates who possibly make an utterance is selectable and that is operated by a selector in a case where the selector selects an utterer from among the plural candidates, specify the utterer from among the plural candidates based on the acquired operation information, and associate the specified utterer with an utterance that is made in a case where the operation device is operated by the selector.

Abstract: An information processing system includes a processor, in which the processor is configured to: specify a notification situation, which is a situation of notification that is related to an utterance of a nearby person who is a person positioned near a target person and that is performed with respect to the target person; and generate control information that causes notification about the specified notification situation to be performed with respect to the nearby person.

Abstract: An information processing system includes one or plural processors configured to acquire a speech image including a speaking person, acquire a supplementary image for supplementing spoken content of the speaking person, the supplementary image being based on the spoken content and not being a text directly representing the spoken content, and perform a control of displaying the supplementary image at a two-dimensional position in the speech image corresponding to a three-dimensional position at which a target to be supplemented is present in the speech image.

Abstract: An information processing system includes a processor, wherein the processor acquires status information that is information related to a status of a nearby person who is a person located around a subject, and when the status specified by the status information acquired is a particular status, the processor generates control information that is used for controlling a device owned by the subject and causes the device to issue a notification indicating that there is a possibility of utterance by the nearby person.

Abstract: An oral composition which comprises a pharmaceutically acceptable carrier, dextranase and .alpha.-1,3 glucanase, said dextranase being present in an enzyme unit ratio of 1:2 to 2:1 relative to said .alpha.-1,3 glucanase. The oral composition according to the present invention exhibits a synergistic effect of dextranase and .alpha.-1,3 glucanase and is highly effective for not only preventing but also suppressing various oral diseases such as dental caries, gingivitis and alveolar pyorrhea.
