Abstract: SYNTHESIZED SPEECH TERMINAL SYSTEM       FOR DATA COMMUNICATION     Abstract of the Disclosure In cooperation with conventional telephones and a private branch exchange, a synthesized speech terminal expedites inquiries to a central data-bank computer by utilizing a microprocessor with memory, a voice synthesizer and a coder/decoder to provide dual tone multifrequency signals or decode the same and cooperatively accommodate data interface operations with the central data-bank computer.  At a telephone, a caller accesses a synthesized speech terminal through the private branch exchange.  Inquiry data packets are then composed in the synthesized speech terminal as the caller actuates the telephone keypad according to programmed instructions.  On completion of an inquiry data packet, the microprocessor actuates the private branch exchange and the connected public telephone network facility to connect the synthesized speech terminal and the data-bank computer.  The microprocessor next controls a rapid inquiry-response exchange, ter-minates the connection then drives the voice synthesizer to announce the response to the caller through the private branch exchange.
