ABSTRACT OF THE DISCLOSURE Disclosed is a multiple-channel voice input/output (I/O) system responsive to two kinds of commands given from a computer in response to each user's request for the voice I/O operation. A voice response unit is connected to m users' channels, where m is a positive integer greater than 1, for performing the voice output operation for at most m users' channels. A recognition unit having n (a positive integer smaller than m) input terminals for performing the recognition of at most n users' voice inputs through the input terminals is connected to the user's channels which have requested the voice input operation. A switch device is disposed between the m users' channels and the input terminals of the recognition unit for connecting at most n users' channels which have requested the voice input operation and selected out of said m users' channels to the n input terminals of the recognition unit in response to a first command of the two kinds of commands given from the computer. A control unit is responsive to each command from the computer for controlling the voice re- sponse unit, the recognition unit, and the switch device, whereby, in response to a second command of the two kinds of commands given from said computer, the control unit controls the voice response unit to perform the voice output operation for a user's channel, and, in response to the first command, the control unit examines an unoccupied input terminal of the recognition unit. and upon detection of the unoccupied input terminal of the recognition unit, the control unit controls the switch device to connect the user's channel to the unoccupied input terminal of the recognition unit. the voice response unit to perform the voice output operation for the user's channel so as to urge the corresponding user to speak, and the recognition unit to perform recognition operation for the user's channel.
