The present invention relates to a home appliance voice apparatus and a voice control method. In particular, a microcomputer, a computer, a voice recording and reproducing unit (IC), and a memory are provided to memorize cautions necessary for using the home appliance. A voice device for home appliances and a voice control method for reproducing and outputting the stored voice signal at the time of transmission. Since the conventional growth growth value is configured in hardware, various components are required, and one model cannot be applied to various home appliances in common, and therefore, suitable speech devices must be configured for each type of appliance and for each model. Difficult to design and complicated, there was a problem that the manufacturing cost increases.

The present invention provides a microcomputer, a voice signal recording and reproducing unit for recording and reproducing a voice signal, and a memory (RAM) in which the voice signal is stored. It can be applied to various kinds of home appliances and models by storing the precautions, etc. of other home appliances in memory, and reusing them when necessary. An object of the present invention is to provide an apparatus and a speech control method, which will be described below in detail with reference to the accompanying drawings.

First, referring to FIG. 1, the foot growth value for home appliances according to the present invention determines a recording or reproducing input signal of a voice signal, and inputs the read / write control of the voice recording and reproducing unit 3 according to the determination result. A microcomputer 1 for recording a voice signal or reproducing the recorded voice signal, and under the control of the microcomputer 1, converts an input analog voice signal into a digital signal and stores it in the memory 5 or in a memory ( 5) a voice recording and reproducing unit 3 for reading and converting an analog voice signal hall and outputting the digital voice signal stored in 5), and a digital voice signal inputted from the voice recording and reproducing unit 3 is stored or stored. It consists of a memory 5 supplied to the voice recording and reproducing section 3.

In the figure, reference numeral R denotes a resistor, LED denotes an operation display light emitting diode, and 2 and 4 denote data buses.

In addition, according to (a) and (b) of FIG. 2, according to the method of controlling a voice for a home appliance according to the present invention performed by the above apparatus, the input terminal AF of the microcomputer 1 is searched and recorded or reproduced. In the first process of judging an input, and the result of the input determination of the first process, the voice input and control unit 3 controls the voice recording and reproducing unit 3 to convert the input voice signal into a digital signal and store it in the memory 5. In the case of the second step and the determination result of the first step, in the case of the playback input, the condition command, the playback start address, the playback end address, and the playback start command are supplied to the voice recording and playback unit 3, and are stored in the memory 5. And a third process of reproducing and outputting the audio signal by accessing the data of the reproduction address from the reproduction start address of the audio signal.

Hereinafter, the voice control operation of the voice signal according to the present invention will be described with reference to FIGS. 1 and 2 (a) and (b).

The microcomputer 1 searches for signal inputs input to the input terminals A-F to determine whether there is a recording signal or a reproduction signal input among the input signals.

As a result of the signal input determination, when the reproduction signal is input, the microcomputer 1 records the voice recording and reproducing unit 3 from the data input / output terminal (DIO) via the data bus (2) to switch the recording mode from the recording mode to the reproduction mode. And input to playback unit 3.

The voice signal recording and reproducing unit 3, which has received this command, is switched to the reproducing mode in which the voice signal stored in the memory 5 is reproduced and output to the output terminal O.

Subsequently, the microcomputer 1 inputs a condition command to the recording and reproducing section 3 via the data bus 2, which is a sampling frequency, sound, and silence of the audio signal. The voice recording and reproducing section 3, which is a command for specifying a condition, determines the sampling frequency, sound and silence of the voice signal by the input command.

After inputting the conditional command as described above, the microcomputer 1 transmits the playback start address to read the audio signal (digital data) stored in the memory 5 from the audio recording and playback section 3 via the data bus 2; Input the reproduction end address and input the reproduction start command to start the reproduction.

At this time, the microcomputer 1 controls the voice enable and the chip enable end (/ CE), the write end (/ WR), and the lead end (/ RD) of the voice record and playback unit 3 with a high signal ('1'). And the reproducing section 3 recognizes the above commands and reads out the audio signal stored in the memory 5.

That is, when the microcomputer 1 controls the voice recording and reproducing section 3 as described above, each control stage (/ CE) (/ WR) (/ RD) of the voice recording and reproducing section 3 is set high. If the low signal '0' (= lead signal) is transmitted to the lead terminal / RD via the data bus 2, is the voice recording and reproducing unit 3 currently performing a different operation? In the case of performing different operations depending on whether or not the operation is performed, the busy signal is supplied to the microcomputer 1 via the data bus 2, and the microcomputer 1 receiving the busy signal transmits the current data. The control unit (/ CE) (/ WR) (/ RD) is judged to be impossible (a state in which the voice recording and reproducing unit 3 cannot recognize the data even though data is transmitted through the data bus 2). Return to the step of supplying a high signal, and if it is not busy, the data bus 2 as described above in the microcomputer 1 Through it is possible to have a voice recording and reproducing unit 3, record / playback mode switch, the command condition, the playback start / end address by transmitting the reproduction start command The voice recording and reproducing unit 3 to the recognition.

The voice recording and reproducing section 3, which receives the playback start command and recognizes it, reads out the digital voice signal stored in the memory 5 via the data bus 4.

That is, as described above, the digital audio signal read from the playback start address inputted from the microcomputer 1 to the playback end address is converted into an analog audio signal and output through the output terminal O. The voice signal, which is the contents of cautions, is uttered.

At this time, the microcomputer 1 searches whether the voice recording and reproducing section 3 has completed reading of the voice signal (lead) by the end address of reproduction, and if the voice recording and reproducing section 3 is not completed, the microcomputer 1 returns to another input terminal AF. When a valid input signal is input, an operation corresponding to another input signal is performed, and when there is no input signal, the audio signal is reproduced up to the reproduction end address.

When the reproduction of the audio signal is completed by the end address, the microcomputer determines whether or not to reproduce it again. The program designer first sets the output frequency of the above-mentioned audio signal in advance. In the case where the computer 1 possesses and replays the audio signal after judging at the time of reproducing the audio signal as described above, the audio signal of the memory 5 is reproduced, outputted again, and reproduced by repeating from the step of transmitting the condition instruction. If not, a reproduction stop command is input via the data bus 2.

The voice recording and reproducing unit 3, which has received the reproduction stop command, stops and ends the reproducing operation of the above-described audio signal.

On the other hand, when the recording signal is input as a result of the determination of the signal input to the input terminal (AF) of the microcomputer 1, the microcomputer (1) is a voice recording and playback unit (DIO) through the data bus (2) ( A command for switching 3) from the playback mode to the recording mode is input to the voice recording and playback section 3.

The voice signal recording and reproducing section 3 receiving this command is converted into a recording mode in which an analog voice signal input to the input terminal I is converted into a digital signal and stored in the memory 5 via the data bus 4. .

That is, when the microcomputer 1 controls the voice recording and reproducing section 3 as described above, each control stage (/ CE) (/ WR) (/ RD) of the voice recording and reproducing section 3 is set high. If the command is transmitted through the data bus 2, the voice recording and reproducing section 3 performs the data bus 2 when it is performing different operations depending on whether it is currently performing a different operation. The BUSY signal is supplied to the microcomputer 1 through which the microcomputer 1, which has received the busy signal, cannot record data even if it transmits data through the data bus (2). And supplying a high signal to each control stage (/ CE) (/ WR) (/ RD) by judging that it is not recognized by the reproduction unit 3, and if not in a busy state, the microcomputer 1 As described above, the phase for supplying a high signal to each control stage (/ CE) (/ WR) (/ RD) Inputs a recording signal (i.e., activates the recording stage / WR low ('0')) to store the digital audio signal converted by the voice recording and reproducing section 3 via the data bus 4 (5) to store.

The poor data in this manner becomes audio signal data reproduced at the time of reproduction as described above. As described above, according to the present invention, the present invention can be applied to various kinds and models of home appliances, and hardware elements can be reduced, thereby reducing manufacturing costs.
