Description

A method for providing speech recognition service, voice dialing service of switching and switching apparatus for conducting thereof}

The present invention relates to a method for providing an additional service by a public telephone network or a private exchange. More specifically, the present invention provides a function of simultaneously or simultaneously performing a voice recognition auto switching service and a voice dialing service from a service providing server.

In recent years, with the development of mobile communication technology, voice recognition and voice processing technology have been developed to activate an auto-exchange service that dials a caller's name without a telephone call by directly dialing a telephone number. In addition, the need for additional services that use voice recognition to obtain information is increasing.

In the conventional voice recognition auto exchange service using a telephone communication network, not only the service manager directly manages the recognized vocabulary information used for the auto exchange, but also changes the phone number information, the department information, and the job title information every time the manager needs to modify it. There was discomfort. In addition, after the recognition vocabulary information is corrected, the speech recognition engine is restarted so that the speech recognition engine can understand it.

In addition, it was difficult to manage the voice recognition auto exchange service and the voice dialing service separately from each other, and it was necessary to always remember two representative telephone numbers.

In particular, in the case of a phone that can store a mobile phone or a shortcut key, a service for making a call using a shortcut key after inputting a phone number to the mobile phone or the phone is activated without dialing the phone number directly. However, in this case, there is a limit on the number of registrations and the hassle that the user must remember the number and input the number individually.

Therefore, there is a demand for a method that can overcome the unreasonableness of the conventional additional services and use the additional services more simply and efficiently.

The present invention has been made to solve the above problems, the first object of the present invention is the caller terminal is connected to the service providing server, the voice recognition auto-switching service and voice dialing service by the public telephone network and private exchange to the receiver terminal Achieve a method of providing a service that is called.

A second object of the present invention is to achieve a method in which a voice recognition auto attendant service and a voice dialing service are simultaneously performed by one software, and a voice dialing service is performed using a specific voice signal or a specific telephone button signal in the auto attendant service. do.

The third purpose of the present invention is to freely input, modify and delete personal information and personal address book through web-based personal information and personal address book management screen, and the input and modified contents are not terminated by the voice recognition engine, that is, without interruption of service. Achieve a method of immediately applying the speech recognition engine.
