The natural language processing server 212 receives text data from the automatic voice recognition server 211, analyzes the received text data to determine a voice command, and sends a response signal based on the determined voice command to the laundry treatment device 10 send to

The natural language processing server 212 may determine a voice command by analyzing the text data received from the automatic voice recognition server 211 according to a natural language processing algorithm.

The natural language processing server 212 may process a natural language, which is a language that humans use daily, according to a natural language processing algorithm, and may analyze a user's intent. The natural language processing server 212 may perform natural language processing on the text data received from the automatic speech recognition server 211 to determine a voice command that meets the user's intention.

The natural language processing server 212 may determine a voice command that matches the user's intention even if the user inputs a voice command in a language used in daily life.

The natural language processing server 212 may transmit a signal corresponding to the natural language processing result, that is, a signal corresponding to the determined voice command to the home appliance control server 230 or the service server 220 .

The natural language processing server 212 communicates with the home appliance control server 230 and performs a corresponding operation if the determined voice command relates to the laundry processing device 10, and the sound command includes the laundry processing device 10 If it is not related to the home appliance, it may communicate with the external service server 220 to perform a corresponding operation.

The natural language processing server 212 determines whether a voice command determined based on the state information of the laundry processing device 10 is supported, and transmits a request signal corresponding to the voice command determined by the home appliance control server 230 or , or a signal indicating that the function is not supported may be transmitted.

The text-to-speech conversion server 213 receives a signal including a text corresponding to the response signal from the laundry processing device 10 , converts the text included in the received signal into voice data, and transmits it to the laundry treatment device 10 . do.

The laundry processing device 10 may receive a voice command input uttered by the user and transmit voice data based on the received voice command input to the voice recognition system 200 .

In addition, after performing the requested operation, the laundry processing device 10 may transmit a signal indicating that the operation has been performed to the home appliance control server 230 .

Also, the home appliance control server 230 may receive a response signal to the control signal from the laundry processing device 10 and transmit processing result information corresponding to the response signal.

In addition, the home appliance control server 230 may transmit the operation result received from the laundry processing device 10 to the voice recognition system 200 and transmit a response signal including the processing result information to the laundry processing device 10 . have.

The voice recognition system 200 receives a signal including an output phrase text corresponding to the processing result information from the laundry processing device 10 , and converts the received output text text into voice data to the laundry processing device 10 . can be transmitted The response signal based on the determined voice command transmitted by the natural language processing server 212 to the laundry processing device 10 may include processing result information.

The laundry processing device 10 may receive a response signal based on the voice command determined from the natural language processing server 212 . Here, the response signal may include text data of a response corresponding to the determined voice command.

For example, when the user inputs a voice command to change the set temperature of the air conditioner, the response signal may include text data indicating that the set temperature is changed.

Meanwhile, the laundry processing device 10 may transmit a signal including text corresponding to the received response signal to the text-to-speech conversion server 213 . Here, the signal including the text corresponding to the response signal may include the output phrase text corresponding to the processing result information.

Meanwhile, the text-to-speech server 213 may convert the text included in the received signal into voice data and transmit it to the laundry processing device 10 . Here, the converted voice data may include a sound source file.

The laundry treatment device 10 may output a voice guidance message based on the voice data received through the speaker.

On the other hand, the natural language processing server 212 determines whether the voice command determined based on the state information of the laundry processing device 10 can be supported by the laundry processing device 10, and if it is supported, the home appliance control server ( 230) may transmit a request signal corresponding to the voice command determined.

In addition, when the natural language processing server 212 cannot support the voice command determined based on the state information of the laundry processing device 10, it may transmit a signal indicating that the function is not supported. A signal indicating that the function is not supported may be included in a response signal based on the determined voice command transmitted by the natural language processing server 212 .

The laundry processing device 10 may request voice data from the text-to-speech conversion server 213 and output a voice guidance message indicating that the function is not supported in the current state.

Depending on the embodiment, it may be determined whether the home appliance control server 230 can support the voice command.

The laundry treatment device control system of the present invention can be used by organically connecting servers that play various roles for natural language voice processing.

The laundry processing device 10 performs operations up to reception and pre-processing of voice commands, and transmission to the server, and the voice recognition system 200 may perform natural language processing such as voice/text conversion, intention analysis, and command identification.

By performing natural language processing in the voice recognition system 200, the laundry processing device 10 can reduce the load on the CPU, memory, etc. of the internal embedded module.

The laundry treatment device 10 may receive voice data including a sound source file from the voice recognition system 200 and output a voice guidance message as audio, thereby responding to the user's voice input with auditory feedback.

The laundry processing device 10 may receive a voice file from the voice recognition system 200 as streaming and reproduce and output a voice guidance message to the user. Accordingly, the laundry treatment device 10 does not need to store various sound source files.

The laundry treatment device control system secures compatibility and connectivity through a plurality of servers, and the final control command utilizes the home appliance control server 230 , so home appliances using Wi-Fi communication through the voice recognition process and the home appliance control server 230 . Conflict between controls and home appliance control through a portable terminal and home appliance control by voice input through the home appliance 300 can be prevented.

In addition, the laundry treatment equipment control system can reduce the load on a specific server depending on one server through an organic connection between servers, and the role of each server is different, so if a problem occurs in a specific server, the same role It is possible to respond easily by linking with other servers that do

In addition, a plurality of servers can be independently updated frequently, which is advantageous for performance improvement.
