Patent US 5,940,795

The data control unit in the voice synthesizing server of the present invention receives from a client data to be processed to synthesize voice, and determines the type of the received data. If the received data are text data, they are outputted to the pronunciation symbol generating unit to generate pronunciation symbols. If the received data are pronunciation symbols, they are outputted to the acoustic parameter generating unit to generate acoustic parameters. If the received data are acoustic parameters, they are outputted to the waveform generating unit to generate voice waveforms, and the generated voice waveforms are sent from the data sending unit to the client. The client receives the voice waveforms from the voice generating server, and outputs the received voice waveforms as voice from the voice output unit.
