Abstract: A control device includes: a storage that stores a dialog model in which a question to a user, a reply candidate to the question from the user and a control content of each electronic device are associated with an input query from the user; an acquirer that acquires environmental data in a surrounding of the user; a calculator that, based on the environmental data, calculates environment predicted data to predict environment in the surrounding of the user after elapse of a predetermined period of time in cases where each control content corresponding to the input query is executed; and a question selector that selects a question corresponding to the control content that maximizes data indicative of a degree of comfort of the surrounding environment of the user in cases where each control is executed based on the environment predicted data.

Abstract: A voice recognition terminal executes a local voice recognition process and utilizes an external center voice recognition process. The terminal includes: a voice message synthesizing element for synthesizing at least one of a voice message to be output from a speaker according to the external center voice recognition process and a voice message to be output from the speaker according to the local voice recognition process so as to distinguish between characteristics of the voice message to be output from the speaker according to the external center voice recognition process and characteristics of the voice message to be output from the speaker according to the local voice recognition process; and a voice output element for outputting a synthesized voice message from the speaker.
