Abstract

A method for identifying voice of mobile communication terminal includes establishing video ¿C audio model by utilizing triphone, registering telephone number, forming triphone data for registered telephone number name or firm name and storing it, inputting user voice, comparing inputted voice data with stored triphone data, dialing out telephone number of inputted voice if identification is successful.

Description

【Technical field】 [0001] This is an invention about speech recognition, especially a mobile communication terminal speech recognition method that can realize the telephone directory search function through speech recognition of inflected words in a mobile communication terminal. 【Background technique】 [0002] Speech recognition technology is a common technology for activating many electrical and electronic devices through voice. If it is used in mobile phones, it will bring great convenience to users. [0003] Among the above speech recognition technologies, the simplest is the speaker-specific isolated word recognition technology, which can only recognize trained speech. When dialing a call by the above-mentioned specific speaker's voice recognition method, at first the required phone number will be registered, and the name of the person corresponding to the phone number will be pronounced once or more than 2 times with the user's voice. That is to say, the user needs to ...
