Description

Home network control service method using speech recognition function {Home network control service method for using speech recognition function}

The present invention is a technology that uses a voice recognition function based on Voice eXtensible Markup Language (VXML) through a telephone network to control home appliances / information products in a home network (hereinafter referred to as a home net) service, and in particular, an existing intelligent network service. Create a VXML-based homenet control scenario in the infrastructure (e.g., voice recognizer / synthesizer / VXML interpreter) and mount it on the home management server (or home gateway). A home network control service method using a voice recognition function for controlling and a computer readable recording medium storing a program for realizing the method.

Control of a home net apparatus using a telephone network in a conventional remote location is made of three types as follows.

First, how to access and control the home auto system by phone, second, how to use the service by interworking the platform provided by the wireless network operator and the home management server of the construction company, and third, voice recognition / There is a method of using a general telephone network with a synthesizer.

Here, the method of accessing and controlling the home auto system by telephone is difficult to accommodate the voice recognition function. First, the voice recognition / synthesis engine and the VXML interpreter should be equipped with a high hardware (H / W) specification, and the second embedded voice processing technology. It still has a weaker limitation than the processing technology in the server, and thirdly, it is difficult to manage such as changing the control scenario when the home equipment is added / modified.

In addition, the method of using the wireless network service provider (that is, the method of using the service provided by the wireless network service provider through the linkage between the platform and the home management server of the construction company) can be controlled through the icon displayed on the screen. While there is an advantage in being able to control and accommodate various control protocols, in order to use the first service, it is necessary to subscribe to the service of a specific wireless network operator and secondly, it is difficult to accommodate the voice recognition function. Simple control (shallow depth of menu), which is an advantage, is difficult, and service change is not easy due to the change of third-party equipment.

Finally, the voice processing method in the home management server is not a VXML-based implementation of the scenario by general coding, so it is not easy to change due to the change of the indoor devices, and a separate call processing function, a voice recognizer, and a synthesizer should be constructed. And there is a disadvantage that the service area is limited.

The present invention has been proposed to solve the above problems, and adds a VXML-based homenet control scenario to an intelligent network service (for example, 1582 voice dial service) and integrates with a home management server (or home gateway). The present invention provides a home network control service method using a voice recognition function and a computer readable recording medium recording a program for realizing the method for controlling a voice recognition-based homenet device by sharing a control protocol. There is this.

The method of the present invention for achieving the above object, in the home network control service method using a voice recognition function, to build a service platform for voice eXtensible Markup Language (VXML) voice processing in an intelligent network and to create a home network service scenario A storage step of storing in the home management server (or home gateway); And a control step of remotely controlling a voice recognition-based home network device by interworking the constructed service platform with the home management server (or home gateway) through the Internet.

Meanwhile, the present invention builds a service platform for voice eXtensible Markup Language (VXML) voice processing in an intelligent network in a home network control service system having a processor, creates a home network service scenario, and creates a home management server (or home gateway). Storage function to save on; And a program recording a program for realizing a control function for remotely controlling a voice recognition-based home network device by interworking the established service platform with the home management server (or home gateway) via the Internet. To provide.

Therefore, the present invention provides the simplicity of use and convenience of creating a control scenario by applying voice recognition and VXML technology for controlling a home network device, and by placing a server having such a function in a generalized communication network called an intelligent network, Regardless of the communication device or communication device, the user can remotely control the home device anytime and anywhere.

That is, the present invention uses an intelligent network as a user access network, adds a voice recognition homenet device control function by using a 1582 voice dial service, which is one of the services provided by the intelligent network, and interworks with a home management server to provide a user with an intelligent network. It is easy to control the device by using simple connection means and voice recognition, and it is characterized by being able to build a homenet control system which is inexpensive and easy for home management companies.

VXML is a standard of voice input / output based voice service scenario proposed by VXML Forum composed of AT & T, Motorola, and IMB. By using voice recognition and synthesis technology, various information can be provided in the form of an interactive voice service capable of voice input and output. Web-based technology can be combined with voice service to enable voice internet service, and provide various services easily and quickly. Provide an environment for doing this.

VXML separates service platforms and service scenarios. The service platform consists of a VXML interpreter, speech recognizer, speech synthesizer, and other tools that interpret the telephone network interface, VXML documents, and activate the speech recognizer and synthesizer according to the flow of the scenario. Once the service scenario is written according to the VXML standard, the voice platform is available through the service platform. In this way, the service platform and the scenario are separated, so it is easy to manage the addition and change of services.

The present invention has a service structure extended to a communication network by using the characteristics of the VXML, that is, the fact that the VXML service platform and the service scenario can be separated. In other words, it establishes a service platform that can process VXML documents in the network (document interpretation, voice recognition / synthesis), and service scenarios are stored as files in the home server or home gateway that manages the actual home network devices. Is a service structure that links to the Internet.

Therefore, it is possible to expand the service globally, and the platform only needs to manage information about the home server irrespective of the device change on the home side, and the home management server can configure the service in a scenario specific to each subscriber. In addition, changes in home devices can be reflected in real-time only by changing the service scenario script.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of a voice recognition home network control service system based on an intelligent network to which the present invention is applied, and shows the structure of an intelligent network and interworking with a voice recognition device unit and a home management server mounted thereon.

In the drawing, "11" is a local exchange, "12" is a Service Switching Point (SSP), "13" is a Service Control Point (SCP), "14" is an Advanced Intelligent Peripheral (AIP), "15" is a VXML script server, "16" represents a home management server, "17" represents a home gateway, and "18" represents a control target device.

As shown in Fig. 1, when a user connects to an intelligent network (1582 voice dial service) using a wired or wireless network, the local exchange 11 knows that it is an intelligent network service and passes the processing to the SSP 12.

Therefore, when the SSP 12 informs SCP 13 that it is a 1582 voice dial service, SCP 13 transmits the location (URL) of the server with the 1582 service scenario (VXML script) to the AIP 14. The AIP 14 receives and interprets the initial service script (logic) 24 from the VXML script server 15 according to the location (URL) of the server with the 1582 service scenario received from the SCP (13). Send out your voice.

In this case, the initial service scenario provides a menu for selecting various services including a homenet service.

Subsequently, when the user ignites the homenet service in the service menu according to the service scenario, the homenet service scenario (26) that is pre-registered for the user using the CID (Caller ID) information provided upon access from the database of the VXML script server 15 ) URL 25 is searched for and connected to the corresponding home management server (or home gateway) 16/17.

The home management server 16 compares the CID with the actual user DB, sends a service scenario specific to each user to the VXML interpreter 23, and starts the home net control service while interpreting the scenario.

The voice control command of the user hears the result recognized by the voice recognition server 21 of the AIP 14 as the synthesized sound through the voice synthesis server 22, and the control command is converted into the voice / control protocol in the home management server 16. The unit 26 is converted to control the corresponding device.

Figure 2 is a service processing procedure of the voice recognition-based home network control service system according to the present invention, showing the detailed structure of the voice processing unit and the location of the service scenario.

As shown in Fig. 2, the AIP 14 in the intelligent network includes voice recognition / synthesis servers 21 and 22 and a VXML interpreter 23, and the VXML script server 15 includes a script file for an initial service scenario. 24) and a service URL DB mapped to a specific CID.

And, the home net service scenario 26, voice / control protocol conversion unit 27 and the user DB 28 is located in the home management server or home gateway (16, 17).

Here, the voice / control protocol conversion unit 27 converts the recognized voice command result code into a homenet device control protocol, and converts the control result code into a voice guidance code.

In addition, the voice / control protocol conversion unit 27 is written in a server-side script (eg, CGI, ASP, JSP, etc.) in the form of a web server program, and the voice / control protocol conversion unit (eg, “light on”) is used. Accordingly, the corresponding script is executed to control the actual device, and the resultant VXML document is transmitted to the VXML interpreter 23. The VXML interpreter 23 operates the speech synthesis server 22 to inform the result (for example, ”Light is on”).

The operation of the home network control service method using the voice recognition function according to the present invention having the structure as described above will be described in detail as follows.

3 is a flowchart illustrating a home network control service method using a voice recognition function according to the present invention.

As shown in FIG. 3, first, an intelligent network service (1582 voice dial service) is connected (301) to receive user authentication (302), and then a request for initial menu guidance and input of a voice command of the user (for example, " Tell me the service "(303).

Subsequently, it is determined whether the user's voice is recognized (eg, referred to as "homenet service") (304). If not, the process proceeds to step 303, where initial menu guidance and user input of a voice command are requested. If the voice is recognized, voice guidance for the submenu is requested and a user inputs a voice command (for example, "Please tell the device to be adjusted") (305).

Therefore, the process of checking whether the menu requested by the user is recognized (for example, "turning on the air conditioner") is performed (306), and if not recognized, a process of requesting input of a voice command of the user by providing voice guidance to the submenu ( 305), and the user's voice is recognized and the target device is started, requesting initial status guidance and control command input (eg, "The air conditioner has been activated." "The current temperature is XX degrees." "Adjust the temperature. Press the #, * buttons ") (307). That is, the above process is a case in which detailed control is required according to the device. As an example of controlling using DTMF, when the air conditioner is operated, the initial state is guided and the temperature control command is waited for.

Subsequently, it is checked if the control command is input (for example, "#") from the user (308), and if not, the voice guidance for the submenu is performed and the user is prompted for the voice command input (305). If a control command is input, the control result is notified (the result is indicated according to the pressed temperature control button. For example, "it has been adjusted to YY degree") (309), and then the control is made as entered (310). If it is not adjusted as entered, the process proceeds to step 307 for requesting initial state guidance and control command input.

4 is an exemplary view illustrating a voice command menu system of a home network control service according to the present invention.

As shown in FIG. 4, under the initial menu 41, there is a menu 42 for a list of in-home controllers, which may have a duplicate name if necessary.

In addition, each control device is divided into a detailed menu 43 according to the space / position to be controlled. The last of the menu is the last state change command 44 of the device, which may be composed of a plurality of commands like the device list. If detailed adjustment is required during the final adjustment command, adjustment (45) can be made in steps using DTMF. DTMF processing for the entire menu can also be performed in parallel with voice commands.

In addition, the submenus 42 to 45 can also be configured with one voice command (for example, turning on a safety lamp).

5A to 5C are exemplary diagrams illustrating a control scenario of a VXML homenet device according to the present invention, and show examples created by dividing the main scenario (main.asp) and the result processing scenario (result.asp).

As shown in Figs. 5A to 5C, in the main scenario, the voice command is recognized according to the user's predetermined grammar 51, and the result processing scenario corresponding to the result is called 52, and the result processing scenario is assigned to the current command. After controlling (54) the actual device, the result is converted into a text (TEXT) sentence (55) and returned to the main scenario.

If there is a change in the device of the home side (for example, currently only the 'light' can be controlled but 'air conditioner' is added), the change of the service scenario is first applied to the air conditioner in the grammar 51 of the main scenario. Add a voice command (e.g. air conditioner on / off), copy / add the script's frame used for lighting control (53), and add the name (air conditioner) and code (e.g. AirCon) of the added device. Change it. In the result processing scenario, copy / add the script frame used for the light control process in the same way, change the code according to the added device, and change only the text sentence about the processing result.

The method of the present invention as described above may be implemented as a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.). Since this process can be easily implemented by those skilled in the art will not be described in more detail.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.

As described above, the present invention provides a simple and transparent service connection and voice recognition by using a universal communication network called an intelligent network as a limitation that a home network service is provided only to a user subscribed to a home device manufacturer or a specific wireless network operator. It is possible to control home devices easily, and it is also effective to reduce service construction and maintenance costs by easily building and changing control scenarios with VXML.
