PURPOSE: A method for controlling audio routings of a TRS(Trunked Radio System) terminal is provided to set up a specific key for controlling the audio routings to automatically perform audio routing functions when the key is pressed while receiving a command call or a telephone call, so as to receive the command call through an earpiece and to receive the telephone call through a speaker by converting an audio path into a speaker mode. CONSTITUTION: If a command call is received, a specific key is examined whether the key is operated to control an audio routing. If so, the audio routing is performed to convert a speaker mode of a sound path into an earpiece mode. The specific key is examined whether the key is operated to control an audio routing while receiving a telephone call. If so, the audio routing is performed to convert the earpiece mode of the sound path into the speaker mode.
