In addition, the voice search mode may be manually executed using a menu or a special key, and may be executed after displaying as shown in FIG. In this case, when the determined word does not exist, when the recognized character is searched in another kind of language dictionary, for example, when the Spanish character is recognized but is searched in the English dictionary or because of an error in the character recognition operation. It may be an error case that is not recognized. In this case, if the character recognition operation generates an error (error) more than a threshold number according to the setting, it may proceed to the voice search mode or execute a manual mode of inputting the corresponding character on the keypad.

The voice search mode recognizes a voice according to a string sequentially input through a microphone MIC or a voice according to a syllable input through the microphone MIC. In addition, the method may extract a feature vector sequence of a voice, weight the extracted feature vector sequence, and search for a vocabulary including the feature vector sequence.

If the user inputs a voice in the voice recognition mode and the voice is input through the microphone MIC, the controller 10 detects it in step 403 and proceeds to step 405. In step 405, the controller 10 controls the memory 29 and the audio processor 25 to convert the input voice data into text data. The controller 10 controls the memory 29 in step 311 to extract a word corresponding to the input voice from an electronic dictionary database (DB), and proceeds to step 313 in which the electronic dictionary corresponds to the extracted word.
