2. The system of claim 1 , wherein the interruption determining circuit determines an allowable time for causing the computer speech output unit to output the computer speech based on the priority setting and the status of the human conversation.
2. The system of claim 1 , wherein the interruption determining circuit determines an allowable time for causing the computer speech output unit to output the computer speech based on the priority setting and the status of the human conversation. 10. The system of claim 2 , wherein the interruption determining circuit determines the allowable time as instantaneous if the priority setting received from the interruption priority setting circuit for the computer speech is greater than a predetermined threshold value, wherein the interruption determining circuit sets the allowable time for interruption as a pause time in the human conversation, wherein the interruption determining circuit sets the allowable lime for interruption as a time when the human speech monitoring circuit detects a decay in the human conversation, and wherein the priority setting includes a periodic schedule for the computers speech output unit to output the computer speech dining the allowable time after a generation time of the periodic schedule occurs.
