ABSTRACT:
A speech synthesizer control circuit for use in a vehicle. The circuit includes a number of features which provide cost effectiveness while maintaining speech synthesizer reliability. One feature of the invention is use of a counter circuit interposed between a control circuit and a memory where messages are stored. The counter is controllably clocked by the controller to create an address within the memory for a particular message. Other features of the invention include control of speech volume, chime generation, and voltage protocals in the speech synthesizer control circuit.
