Abstract
A speech synthesizing circuit includes a speech synthesizing integrated circuit chip and an audio synthesizing integrated circuit chip. The speech synthesizing integrated circuit chip has a microprocessor, a speech synthesizer, a programmable memory, an input/output port, and a speech address register. The audio synthesizing integrated circuit chip has a microprocessor, an audio synthesizer, a programmable memory, an audio data storage memory, and an input/output port. The input/output port of the speech synthesizing integrated circuit chip is connected to input/output port of the audio data storage memory of the audio synthesizing integrated circuit chip. The programmable memory of the speech synthesizing integrated circuit chip is programmed to cause the microprocessor of the speech synthesizing integrated circuit chip to retrieve speech data from the audio data storage memory of the audio synthesizing integrated circuit chip for speech synthesis by the speech synthesizer of the speech synthesizing integrated circuit chip. The programmable memory is programmed by providing software simulations of instructions preprogrammed into the speech synthesizing integrated circuit chip during manufacture thereof that cause an address to be loaded onto the speech address register, and cause speech data located at an address stored in the speech address register to be obtained. The software simulations cause an address to be loaded into the audio synthesizing integrated circuit chip and cause speech data to be obtained by the speech synthesizing integrated circuit chip from the external memory integrated circuit chip at an address stored in the external memory integrated circuit chip.
