PURPOSE:To enable to conform to a neighboring environmental conditions by a method wherein a voice uttering part volume for giving voice instruction to a cooker user or operator can be set by key operation. CONSTITUTION:A voice generating part 8 consists of a control part 9, ROM10, voice composing part 11, operation amplifier 12 and a speaker 13, the instruction contents for an operator memorized as digital signals by ROM10, for example the voices ''Add salt'', ''Mix up'' and the like, are uttered. Together with connecting a serial circuit of a resistor 16 of resistance value R1 and the first FET17 and a serial circuit of a resistor 18 of resistance value R1/2 and the second FET19 in parallel with the resistor 15 of the resistance value R1 connected with the operation amplifier 12 outputs OB7, OB8 of mu COM1 are put in the first, the second FET17, 19 and a keyboard 2 is provided with a volume key. Thereby the volume from the voice generating part can be selectively set by key operation. |
