PROBLEM TO BE SOLVED: To recognize a predetermined voice during a speech and to provide information (e.g., time or the like) relating to the recognized voice as a voice during the speech. SOLUTION: A voice signal input from a microphone 29 is converted into a digital signal by an A/D 28 and given through an adder 23 to a voice recognizing unit 20 thereafter, and a phrase registered beforehand is detected. If a phrase such as "What time is it now ?" is detected, for example, time data of a clock 16 are read out by a control unit 12 and given to a voice synthesis unit 18. The time data is converted into synthetic voice data representing a time by the voice synthesis unit 18 and given to an adder 21. In the adder 21, the synthetic voice data is superimposed on voice data of a partner of a speech output from a decoder 17, converted into an analog voice signal by a D/A 26 and output from a speaker 27.
