1. A computer speech output control system, comprising: a computer speech output unit configured to output a computer speech; a human speech monitoring circuit configured to determine whether a human conversation is occurring; an interruption priority setting circuit configured to set a priority setting for when the human conversation can be interrupted by the computer speech; and an interruption determining circuit configured to determine whether to cause the computer speech output unit to output the computer speech based on the priority setting and a status of the human conversation, wherein the human conversation comprises human-to-human speech, wherein the human-to-human speech includes ambient speech not directed to an electronic device, wherein the human-to-human speech comprises speech between two humans that is not via the electronic device, wherein the interruption determining circuit sets an allowable time for interruption as a pause time in the human conversation, and causes the computer speech output unit to interject into the human conversation with the computer speech during the pause time, wherein the pause time is determined from pauses detected in the human-human speech.
11. The system of claim 1 , wherein the human speech monitoring circuit is further configured to identify whether a primary user of the system is engaged in the human conversation, and wherein the interruption priority setting circuit includes a primary user priority setting in which a specific conditional interruption preference is set up based on tire primary user being engaged in the human conversation.
