1. A mobile communication terminal comprising:
- a display unit for displaying a character;
a voice input unit through which a speech sound is inputted;
a storage unit for storing reference phoneme models of respective feature vectors of phonemes of the input speech sound; and
a controller for segmenting the speech sound inputted for the displayed character into the phonemes, extracting respective feature vectors from the phonemes, and generating and storing the reference phoneme models based on the extracted feature vectors respectively.

Abstract
Disclosed is a mobile communication terminal using a phoneme modeling method for voice recognition. The terminal includes a voice input unit, a storage unit and controller. The voice input unit is used to input a speech sound. The storage unit stores reference phoneme models of respective feature vectors of phonemes, produced by a speech sound inputted by the user. The controller segments the input speech sound into phonemes, extracts respective feature vectors from the phonemes, and performs pattern matching between the extracted feature vectors and the reference phoneme models, so as to recognize the input speech sound.
