Abstract

A multiple channel voice I/O system including a control device and switching mechanism for enabling the system to handle a greater number of user channels than there are recognition inputs. The control unit responds to two types of commands from a host system, the first type indicating a voice output operation and the second type indicating a voice input/recognition operation. During voice output for any user channel, that channel is not connected to any input terminal of the recognition unit. During voice input/recognition operation, the control unit searches for an unoccupied input terminal and connects it to a user channel.
