PROBLEM TO BE SOLVED: To take proper measures even when a plurality of speech processors carry out speaker output or microphone input closely to each other. SOLUTION: Speech processors X which are used closely to mutually send and receive information (information representing features of speeches) regarding speeches being outputted by speakers 13 of the respective processors and speeches being inputted to microphones 12 to each other and a device in microphone input detects whether the speech of a transmission source of received information is mixed with a speech being inputted to a microphone according to the received information. Further, a device in speaker output detects whether the speaker output of itself gives disturbance to the microphone input of the transmission source of the information on the basis of the received information. Consequently, a device as the causing source of disturbance is given notice of suppressing a speech as a disturbance and a processor having received the information takes proper measures by spontaneously lowering the speaker output level.
