PURPOSE: A multi voice modulation output device of a radio pager is provided to offer reception service information, time information and option functions of the pager through a variety of voices. CONSTITUTION: A multi voice modulation output device of a radio pager includes a central processing unit(210), a key input unit(212), a frequency generator(213), and a frequency mixer(214). The central processing unit displays a plurality of voice output modes on the screen of a liquid crystal display and reads voice data of a memory to convert the voice data into an analog voice frequency. The key input unit has a voice mode selection key that selects a voice output mode on the screen in order to output voice data corresponding to information displayed on the screen. The frequency generator generates a modulation frequency corresponding to the voice output mode selected by the central processing unit. The frequency mixer mixes the generated modulation frequency with the analog voice frequency to output the mixed frequency to a speaker. |
