Abstract

PURPOSE:To prevent a noise from mixing into a calling sound signal by eliminating the need for a microphone with a press-to-talk switch when a party station is called, by atuomatically sending the calling voice signal from a sound synthesizing processor added to a main radio equipment. CONSTITUTION:Radio equipment 4 with a voice synthesizing processor connected with microphone 1 and loudspeaker 3 is provided with calling voice selection buttons 5. When selection button 5 is operated corresponding to a party station, the digital signal that corresponds to the party station is read out of memory 6 in the processor and restored to a signal for digital display of a voice signal of digital encoder 5. This restoration output is converted by D/A converter 8 into an analog signal, which is modulated by transmission part 9 to send the calling voice signal to the party station. Thus, the need for a microphone with a press-to-talk switch is eliminated and noises are prevented from mixing into the calling voice signal.
