<p>PURPOSE:To enhance the usability of a heater with a voice sensor by providing a ready displayer showing the state of permitting to receive the voice sensor input. CONSTITUTION:In a controller 11, input signal from an input means 12, e.g., key board, etc., is stored in a memory 13 and data are displayed on a displaying means 14 called by the controller 11 during the heating operation. In a voice input unit 16, the input voice of a mike 8 is amplified, converted into digital data through a feature parameter extractor 17, and put in a parameter comparator 18. In the comparator 18, the data are compared with the registrated parameter group of a parameter memory 19, and when the minimum value of the distance with feature parameters is below a threshold value, a single word corresponding to the parameter is output as a recognition single word to the controller 11, and a ready display is made on the ready displayer 20 to show a voice recognition permittive state. By this, even when both hands are full, the heater can be easily operated.</p> |
