A language analyzer (2) performs speech recognition on a speech input by a speech input unit (1), specifies a possible word which is represented by the speech, and the score thereof, and supplies word data representing them to an agent processing unit (6). The agent processing unit (6) stores process item data which defines a data acquisition process to acquire word data or the like, a discrimination process, and an input/output process, and wires or data defining transition from one process to another and giving a weighting factor to the transition, and executes a flow represented generally by the process item data and the wires to thereby control devices belonging to an input/output target device group (5). To which process in the flow the transition takes place is determined by the weighting factor of each wire, which is determined by the connection relationship between a point where the process has proceeded and the wire, and the score of word data. The wire and the process item data can be downloaded from an external server.
