Abstract

PURPOSE:To enable to operate an audio recognizing means in a reliable manner, by displaying the level of speech according to the level of speech input, and applying inputs while ascertaining the volume of audio signal given actually by the user visually. CONSTITUTION:A heat source 9 for heating a substance to be heated is controlled by a controller 11, and the output, heating time and other instructions are given to the controller 11 from an input means 12. These instructions are stored in a memory 13 and displayed by a display means 14. Further, the heating apparatus of this invention comprises a speech recognizing means 16 which consists of a speech input section 17 including a microphone 8, a feature parameter extracting section 18, a parameter comparing section 19 and a parameter memory 20. The signal level of the input speech signal given to the means 16 is displayed by a speech input level display means 21. By thus instructing a complicated heating sequence by speech and replacing manipulation of a keyboard by speech, it is enabled to improve usability of the heating apparatus and to ascertain the level of speech input directly by the user.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device having a voice recognition means, and a level display according to the voice input level allows the user to input while visually confirming the voice volume, thereby ensuring voice recognition. It's something I'm trying to make work.

Conventionally, in a heating device 9 having a digital control unit, such as a microwave oven Vζ using a microconbeater, a heating sequence corresponding to a specific menu is stored in advance in memory, and heating is performed according to a number manually set by a key. Select a sequence and run it. However, as the number of menus increases and the number of selection numbers increases, it becomes easy to make mistakes in setting the values, resulting in a completely different heating sequence being executed, and problems such as the large number of keys lined up on the operation panel and operation errors. It came out.

The present invention uses voice recognition means to input words corresponding to the direct heating sequence, that is, many names, and key names on the operation panel, and also displays the voice input level. This means that the appropriate input level can be visually checked at all times, so that voice recognition can be operated reliably. 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, and the front 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 includes a keyboard group 4 and an output display group 6. , a time display section 6, and an audio input level display section 7 are arranged, and a microphone 8 for audio input is connected to the side surface of the main body 1.

The user of the heating device is "H" on keyboard group 4.

rMHJ, rMJ, rMLJ, r-LJ, rWJ (7)
After pressing either button to select the heating output, select “10MJ.

Press the "1M", "10S", and "1S" keys to set the heating time, and press the "5TAJ" key to start heating. This is manual heating, and depending on the heating menu, you can set 2 stages or 3 stages. Yes, these operations can be performed in the same way using the microphone 8.

Next, in the case of automatic heating, if you input the word corresponding to the heating sequence, that is, the name of many, from the microphone 8,
The settings of the first stage are immediately displayed on the time display section 6 and the output display section 6.

The audio input level display section 7 allows audio input to be performed while visually checking the level so that the level is optimal both above and below according to the volume of the audio input from the microphone 8.

FIG. 2 is a block diagram according to the present invention. 1. The heating source 9 corresponds to a magnetron in a microwave oven, and is controlled by an output control means 10; Execute. The output control means 1o is a controller 11
It is controlled by the PWR signal issued by the

The controller 11 temporarily records the key input signal inputted from the input means 12 such as a keyboard into the memory 13 using the key strobe signal KSTB. Data such as the heating time or output i'Tt, 7JIl during thermal operation. The data is called again into the controller 11 and becomes the basic data for timer control or output control.
The controller 11 outputs display data to the display means 14 to perform a predetermined display.

Two or more types of heating/can data is stored in the sequence memory 16 and called by the controller 11 to serve as basic data for an automatic heating sequence.

The voice recognition means 16 includes a voice input section 17 including a microphone f3, a feature parameter extraction section 18, and a parameter comparison section 1.
9, a parameter memory 2o. The audio input section 17 amplifies the audio signal input from the microphone 8, and the feature parameter extraction section 18 extracts phonetic features contained in the audio signal and converts it into digital data, such as a filter bank or an analog multiplexer. ,
Frequency spectrum analysis using an AD converter or the like can be easily realized. The parameter comparison unit 19) compares the feature parameter groups of various speech words registered in advance in the parameter memory 20 with the feature parameters of the unknown speech inputted from the feature parameter extraction unit 18, and determines the relationship between each feature parameter. The distance is calculated, and if the minimum value of this distance is less than or equal to a threshold value (preset), the word corresponding to the feature parameter, that is, the menu, is output to the controller 11 as a recognition result. If it is above the threshold, it is assumed that the recognized word does not exist in the parameter memory 2o, and no output is output, but a reject signal is output.Therefore, if the name of the heating menu is input from the microphone 8, the recognition result is sent to the voice recognition means 16ij. Based on this recognition result, the controller 11 reads out the heating sequence data from the sequence memory 15 and sets automatic heating.

The audio input level output means 21 generates output data to the audio input level display means 22 from the output signal of the audio input section 17, that is, the amplified signal of the audio input signal.

For example, the audio input level display means 22 may include a plurality of LEDs.
If the audio input level output means 2 is composed of
It can be easily realized with 1ij AD converter and LED driver.

The controller 11 has a memory 13 and a sequence memory 16.
The parameter comparison section 19 can also be easily realized using a microcomputer.

As described above in detail, according to the present invention, by using the voice recognition means and the voice input level display means,
The user can input complex heating sequences or operate the keyboard by voice, greatly improving the usability of the heating device, and since the user can visually check the voice level, voice recognition can be used reliably. I can do it.
