Abstract
Heating apparatus equipped with a sensor element for sensing or estimating the state of a substance being heated, for example, a temperature probe containing a temperature sensor such as a thermistor in one end of a metal tube or a humidity sensor sensitive to vapor emanating from the substance being heated. Information data relating to the handling of such a sensor element or instructing an appropriate heating sequence or process selected on the basis of the sensed state of the substance being heated is selectively read out from a voice data memory to be synthesized into voice information in a voice synthesizer such as a PARCOR synthesizer, and the voice information is announced to the user at a predetermined time. The user hearing the message can therefore manipulate the apparatus in such a way as to compensate for the inherent defect of the sensor element, and even a menu requiring a very delicate procedure can be successfully cooked without any heating failure.
