A mobile communication terminal and text-to-speech method. The mobile communication terminal includes a display unit for displaying at least one object on a screen; a controller for identifying a depth of an activated object on the screen and finding a speech data set mapped to the identified depth; a speech synthesizer for converting textual contents of the activated object into audio wave data using the found speech data set; and an audio processor for outputting the audio wave data in speech sounds. As a result, textual contents of different objects are output in different voices so the user can easily distinguish one object from another object.
