PROBLEM TO BE SOLVED: To provide an exhalation switch system which makes bidiretional communication possible between the side of an exhalation message sender and other persons by improving one-way communication from the side of the exhalation message sender. SOLUTION: A message by exhalation is transmitted to an external device 300 by a transmission message generation means 201. An external message from the external device 300 is received by an external message receiving means 203 and the received external message is announced by an external message annunciation means 204. This allows the message sender by exhalation to check to see if his intention is conveyed correctly to the counterpart. The external message previously transmitted from the external device 300 is received by the external message receiving means 203 and announced by the external message annunciation means 204 and a message by exhalation can be transmitted to the external device 300 by the transmission message generation means 201. This also allows a person on the side of the external device 300 to check to see if own message is conveyed correctly. |
