PURPOSE: A system for supplying stock information via communication is provided to process stock information such as many news agencies, newspaper publishing companies, security companies, and private information with voices, so as to supply the stock information to clients in real time. CONSTITUTION: When a monitor personnel monitors stock information supplied from many news agencies and media, and broadcasts the stock information as voices, the broadcasted voices are converted into voice data in a database server to transmit the voice data to a client terminal through a communication network. The voice data is converted into voices to which a client can listen via a voice outputter of the client terminal. If a voice signal is outputted from the voice outputter of the client terminal through one channel, a radio transmitter(100) modulates the voice signal into a radio frequency signal of a mono voice to transmit the modulated voice signal. If voice signals are outputted through many channels, the radio transmitter(100) modulates the voice signals into radio frequency signals with a stereo voice to transmit the modulated voice signals. A radio receiver(200) demodulates/converts radio frequency signals of the transmitted mono or stereo voice into a mono or a stereo voice to which the client can listen through a speaker or earphones, to output the mono or the stereo voice.
