Abstract:
A speech synthesizing circuit, comprising:a speech synthesizing integrated circuit chip having a microprocessor, a speech synthesizer, a programmable memory, an input/output port, and a speech address register for storing an address containing speech data, the speech synthesizing integrated circuit chip including an instruction, pre-programmed into the speech synthesizing integrated circuit chip during manufacture thereof, that, when executed, can cause an address to be loaded into the speech address register; andan external memory integrated circuit chip, the input/output port of the speech synthesizing integrated circuit chip being connected to the external memory integrated circuit chip;the programmable memory of the speech synthesizing integrated circuit chip being programmed to cause the microprocessor to retrieve speech data from the external memory integrated circuit chip for speech synthesis by the speech synthesizer, the programmable memory being programmed by providing a software simulation of the instruction that can cause an address to be loaded into the speech address register, the software simulation causing the address to be loaded into the external memory integrated circuit chip without reliance on execution of the instruction pre-programmed into the speech synthesizing integrated circuit chip to load the address;wherein the external memory integrated circuit chip comprises an audio synthesizing integrated circuit chip selected from the family of SP chips.
