Abstract
A heating apparatus capable of receiving several voice commands which comprises a voice recognition circuit and is improved from a systematic point of view, so that erroneous recognition in receiving a starting command and a stop command is effectively prevented, and the heating apparatus further comprises a stop button to produce an input signal which is given priority over any input voice commands and which fulfills an equivalent function to the stop command thereby enabling of stopping a heating operation by pushing the stop button, even when the voice recognition circuit does not correctly work or a voice command can not be acknowledged by the voice recognition circuit due to large acoustical noises coming from the circumference around the heating apparatus.
