Voice actuated heating apparatus
First Claim
1. A heating apparatus comprising:
- (a) an enclosure case having therein a heating chamber in which an object to be heated is to be placed, the enclosure case having a door at an opening of said heating chamber,(b) a heating means for radiating heating energy into said heating chamber,(c) detecting means for measuring physical data of heating conditions of said object,(d) a speech recognition and control circuit, and(e) a display means for displaying operation states of said heating apparatus,wherein said speech recognition and control circuit comprises;
(f) a voice command input means including a microphone for transforming a user'"'"'s voice commands into command input signals,(g) a pattern analyzer for frequency-analyzing said command input signals to divide them into input pattern signals each associated with a predetermined frequency band, subsequently sampling said input pattern signals, and carrying out A/D conversion thereof to produce pattern-analyzed digital data,(h) an input pattern memory for memorizing said pattern-analyzed digital data in a form of time sequential patterns,(i) a reference pattern memory for storing time sequential reference pattern data as reference patterns,(j) 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 generating a signal indicative of an affinity degree of the comparison, and for producing predetermined recognition codes corresponding to recognized voice commands, when said signal of said affinity degree for one respective voice command among said user'"'"'s voice commands is more than a present signal level,(k) a control circuit part including a program memory in which a plurality of heating sequences are preliminarily stored prior to the operation of said heating apparatus, and for selecting and presetting the selected one of said heating sequences based on said predetermined recognition codes, and for controlling operations of said heating means in a manner to heat said object according to said preset heating sequence, and wherein that said display means displays said selected heating sequence.

Abstract
A heating apparatus, such as an electric oven or an electronic oven including a voice recognition part which recognizes voice command of the user and produces a recognition code by receiving the voice command and performs operation by the voice command. Heating sequences are preliminarily stored in a memory of a control part, and one of them are selected by a recognition code produced by the voice recognition code, and preset in the memory. Heating members are controlled in a manner to heat the heating object according to the preset heating sequence. Such selection and presetting of the heating sequence is performed only when at least two sequential voice commands are fed to the voice recognition part in a predetermined order.
