A semiconductor network is interposed between first and second multiple-port interfaces each having high-voltage, intermediate-voltage and ground ports to form a switch assembly. The system includes a continuous speech recognition digital signal processor, a programmable microprocessor interfaced therewith, voice input and user feedback mechanisms, including audio andor video feedback. To this end, the fruits and heatedconditioned, double-ground, individualized on a baffle plate and the hulls are removed.
