Therefore, in order to overcome these problems, when a user inputs a specific word for a counterpart who wants to talk without using the keypad of the mobile phone, the caller's and receiver's calls are made by calling and dialing a phone number corresponding to the input voice from the corresponding database. A system has been developed to enable this.

In other words, in order to use voice recognition dialing, information related to a person's name and a phone number must first be stored in an exchange server. At this time, in order to store the name and phone number related information in the exchange server, the user must manually enter the desired telephone number by accessing the exchange server. After storing the name and phone number related information in the exchange server, the user dials the exchange server for voice dialing, speaks the name of the person he / she wants, and makes a call according to the recognized result.

However, the method of using such a system is inconvenient that the user manually inputs all the desired numbers and the corresponding user's voice by using the Internet or a dedicated application when storing the life and phone number related information on the exchange server. have.

In addition, even when a phone number is newly added or updated, there is a problem that a user must manually add or modify it every time.

The present invention has been made to solve the above problems, the object of which is that the contents stored in the phone book of the user's mobile phone is transferred to the database of the exchange server and stored and the mobile phone user speaks a specific name or alias, the exchange server is variable It converts text into a text through a vocabulary speech recognizer and detects the corresponding phone number in the user's phonebook previously stored in the server to perform automatic dialing, providing a large amount of phone number storage space and converting the current user's voice into a variable vocabulary voice. It is to provide a voice recognition dialing system and method using the phonebook data transmitted to the exchange server to dial directly compared to the pre-stored text through the recognizer.

In addition, another object of the present invention is that if the user is newly added or updated to the phonebook data of the user's mobile phone reflects in real time to the phonebook data of the exchange server to add or modify when the user changes the contents of the phonebook data It is to provide a voice recognition dialing system and method using the phonebook data transmitted to the exchange server that does not need to modify the contents of the exchange server for each user.
