ABSTRACT:
A speech synthesizing circuit includes a speech synthesizing integrated circuit chip and an external memory integrated circuit chip. The external memory chip may be an audio data storage chip or an audio synthesizing chip. The chips are connected through an input-output port on each chip, and the microprocessor of the speech synthesizing chip retrieves speech data from the audio data storage memory of the audio synthesizing chip. Access to the memory of the audio synthesizing chip is accomplished by software simulations that modify the functions of instructions pre-programmed into the speech synthesizing chip during manufacture. The preprogrammed instructions cause the address of speech data to be loaded into a speech address register and the software modifications cause an address to be loaded into the audio synthesizing chip, by which the speech synthesizing chip will retrieve speech data from external memory at an address stored in the external memory chip. Alternatively, the instructions to deliver data to the speech synthesizing chip may be programmed into the audio synthesizing chip. A speaker is connected to balanced speaker driver outputs of the speech synthesizing chip and also to a single-ended speaker driver of the audio synthesizing chip.
