Abstract

PURPOSE:To make remote control easy, by applying a wireless microphone and a voice recognition device incorporating a receiver. CONSTITUTION:This device consists of a controller 11 controlling a heat source, an input device 12, such as a key-board, a memory 13 storing an input information and a voice recognition device. In the voice recognition device 15, a voice signal from a wireless microphone 7 is received by a receiver 16, amplified by a voice application part 17, an extracted phonemic distinctive feature by a distinctive feature parameter extraction part 18 is converted into a digital data which is compared with a distinctive feature parameter group of a registered voice word from a parameter memory 20 by a parameter comparator part 19, and a word corresponding to an extracted parameter is applied to a controller 11 as recognition output.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device in which heating conditions can be easily set and operated even from a distance using a voice recognition device including a wireless microphone and a receiver.

Conventionally, heating devices with digital control units, such as microwave ovens using microcomputers, have been configured to have two combinations of output and time in order to improve the cooking quality.
We also had to set up three stages.

Therefore, since the microwave oven was set with a cookbook in hand, mistakes were often made. Additionally, when the microwave oven needs to be stopped or restarted during heating, both hands are occupied with other cooking tasks, making it difficult to operate the microwave oven.

The present invention is a heating device configured to use a voice recognition device including a wireless microphone and a receiver so that the heating device can be easily set and operated from a remote location and even when both hands are occupied.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a perspective view of the main body of the heating device according to the present invention. The front surface of the heating device main body 1 is provided with a door 2 that can be opened and closed, and an operation panel 3. The operation panel 3 has a keyboard group 4. An output display section 59 and a time display section 6 are arranged. Also, main body 1
A receiving antenna 8 for the wireless microphone 7 is installed at the rear of the microphone. Wireless microphones have a clip that allows them to be attached to clothing.

If you are a user of the heating device, press "H" on keyboard group 4.

Press any of the rMJ, 'rLJ, rWJ, or rDJ keys to set the heating output, then press keyboard group 4.

Therefore, even if you are far away and both hands are occupied, if you speak into the wireless microphone 7, it will be received by the antenna at the rear of the main unit 1, the voice recognition device built into the main unit 1 will recognize the voice, and then press the key. You can do the same thing.

FIG. 2 is a block diagram according to the present invention.

The heating source 9 is a magnetron in a microwave oven,
It is controlled by the output control means 1o to execute a predetermined output and heating time. The output control means 10 is controlled by a PWR signal issued from a controller 11.

The controller 11 temporarily stores, in the memory 13, a key input signal taken in from an input means 12 such as a keyboard based on the key strobe signal KSTB. This data such as heating time or output is called back into the controller 11 during the heating operation and becomes basic data for timer control or output control. In addition, the controller 11 has a display means 1.
Display data is output to 4 to perform a predetermined display.

The voice recognition means 16 receives the voice signal transmitted from the wireless microphone 7, for example, an FM microphone, with the FM antenna 8, demodulates it with the receiver 16, and
The audio input section 17 amplifies the signal.

The feature parameter extraction unit 18 extracts the phonetic features included in the audio signal sent from the audio input unit 17 and converts it into digital data. Spectral analysis etc. can be easily realized. The parameter comparison unit 19 compares the feature parameter group of the audio word registered in advance in the parameter memory 2o with the feature parameter extraction unit 1.
The feature parameters of the unknown voice input from step 8 are compared with each other to find the distance to each feature parameter group, and if the minimum value of this distance is less than the threshold, the word corresponding to that parameter is recognized by the controller. The code of the word is output to 11, and if the condition is not met, an ejection signal is output.

The wireless microphone 7 has a clip and can be attached to clothes near the mouth, allowing both hands to be used freely.Furthermore, since the SN ratio is improved against ambient noise, the recognition rate is also improved.

As described in detail above, according to the present invention, a voice recognition device using a wireless microphone allows the heating device to be set and operated from a distance or at any time even when both hands are occupied. There are benefits.
