First Claim
1. A heating apparatus comprising:
- an enclosure case having therein a heating chamber adapted to receive an object to be heated, said enclosure case having a door at an opening thereof,a heating means for generating heating energy in said heating chamber,a voice command input means for transforming a user'"'"'s voice command into a command input signal,a pattern analyzer for frequency-analyzing said command input signal by deriving therefrom input pattern signals for a predetermined number of frequency bands, subsequently sampling said input pattern signals, and carrying out A/D conversion thereof thereby producing pattern-analyzed digital data,an input pattern memory for storing said pattern-analyzed digital data in a form of time sequential patterns,a reference pattern memory for storing time sequential reference pattern data as reference patterns,a recognition processing circuit for comparing said pattern-analyzed digital data stored in said input pattern memory with said time sequential reference pattern data stored in said reference pattern memory, and for outputting a signal indicative of an affinity degree of the comparison, andan output control circuit for issuing a predetermined control signal when said affinity degree determined by said signal from said recognition processing circuit is higher than a predetermined affinity degree,said reference pattern memory comprising a first address part which contains first reference pattern data corresponding to a first voice command for stopping a heating operation of said heating means, and a second address part which contains second reference pattern data corresponding to a second voice command for starting said heating operation of said heating means,said recognition processing circuit being constituted to carry out the comparison of said pattern-analyzed digital data with said first reference pattern data corresponding to said first voice command, in advance of the comparison of said pattern-analyzed digital data with said second reference pattern data corresponding to said second voice command.

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.
