Centrally controlled voice synthesizer

A centrally controlled voice synthesizer comprising

• a memory which is preprogrammed with voice data, melody data, address data, and control data;
• an input processor for receiving an external signal and outputting a triggering signal;
• a clock generator for generating clock signals;
• a logic control unit for receiving the clock signal from the clock generator, receiving the triggering signal from the input processor, and fetching the voice data, the address data, and the control data from the memory upon receipt of the triggering signal;
• a decoder for decoding the data fetched from the memory via the logic control unit and generating a control signal;
• a rhythm generator for outputting a rhythm signal to the logic control unit upon receiving the clock signal from the clock generator and the control signal from the decoder;
• a digital-to-analog converter connected to the memory for converting digital voice or melody data from the memory to analog voice or melody signal;
• and
• a transistor connected to the digital-to-analog converter for amplifying the analog voice signal and driving an external speaker to emit corresponding voice wherein the memory has the data therein separated into a section heading, a word heading, and a word data table, where the section heading defines a heading address, voice, triggering mode, and output control data.
