Abstract

A method for providing a proxy speech mode for a dumb person in a mobile terminal is provided to enable a speech-handicapped person to smoothly execute calls such as normal persons through a mobile terminal having a TTS(Text To Speech) engine. If a speech path is formed, a speech-handicapped person's mobile terminal judges whether the present mode is a proxy speech mode(S11,S13). In case that the present mode is the proxy speech mode, the mobile terminal outputs a voice signal, transmitted from the other side's mobile terminal, through a speaker(S15). At this moment, the speech-handicapped person's mobile terminal judges whether a text signal is inputted from an external keyboard(S17). If a text signal is inputted from the external keyboard, the speech-handicapped person's mobile terminal converts the inputted text signal into a voice signal using a TTS engine, temporarily stores it, and transmits it to the other side's mobile terminal(S19,S21).
