A speech system includes a processor configured to acquire a situation value indicating a situation involving a plurality of persons based on pieces of emotion information indicating emotions of the plurality of persons, and control a speech of an object based on the acquired situation value.
First claim
Opening claim text (preview).
What is claimed is: 1 . A speech system comprising a processor configured to: acquire a situation value indicating a situation involving a plurality of persons based on pieces of emotion information indicating emotions of the persons; and control a speech of an object based on the acquired situation value. 2 . The speech system according to claim 1 , wherein: the processor is configured to estimate an emotion of each of the persons based on a facial expression of the person and to estimate the emotion of the person based on a voice of a speech of the person; and the emotion information is emotion information obtained when emotion information estimated based on the facial expression and emotion information estimated based on the voice of the speech agree with each other. 3 . The speech system according to claim 1 , wherein the object is a virtual object or a real object. 4 . The speech system according to claim 1 , wherein the processor is configured to acquire the situation value based on a conversational situation involving the persons as well as the emotion information. 5 . The speech system according to claim 1 , wherein the situation value indicating the situation involving the persons is a value representing a level of a quality of an atmosphere of an environment where the persons are present. 6 . The speech system according to claim 5 , wherein the situation value is a value indicating one grade out of a plurality of grades into which the quality of the atmosphere is classified. 7 . The speech system according to claim 1 , wherein the processor is configured to decide whether to cause the object to make the speech based on the situation value. 8 . The speech system according to claim 7 , wherein the processor is configured such that, when the processor acquires a situation value indicating that an atmosphere of an environment is bad, the processor decides to cause the object to make the speech. 9 . The speech system according to claim 7 , wherein the processor is configured such that, when the processor acquires a situation value indicating that an atmosphere of an environment is good, the processor decides not to cause the object to make the speech. 10 . The speech system according to claim 1 , wherein the processor is configured to estimate the emotions of the persons by identifying individual facial expressions in face images of the persons, which are extracted from an image captured by a camera.
