A wireless communications device that alerts a user to a predetermined event includes a transceiver, a speaker, memory, and a controller. First and second pre-recorded audio files are stored in the memory, and may be, for example, pre-recorded music and the user's pre-recorded voice. When the device receives an incoming call, for example, the controller combines the first and second audio files to form a combined audio signal. The controller then plays the combined audio signal through the speaker for the user as a personalized ring tone.
