uick rough draft of the speech system. The basic operation is controlled by a 48Mhz micro controller which acts as a serial relay to the tts256 IC, much the same way an ftdi chip would. The MSGEQ7 is controlled and interpreted by the pic16F1459.

Since the design is so simplistic, not sure I plan on etching a board for it, and just putting it onto a veroboard with some IC sockets.

Things may change, but lets give this rough back of the napkin schematic a try. :)
