Abstract:
1. A condition notification method for notifying a used condition of a simplex communication apparatus by using a light-emitting device attached to the simplex communication apparatus, the method comprising: a communication-mode determination step of determining whether a communication mode of the simplex communication apparatus is a transmission mode or a standby mode; a sound pick-up state determination step of determining a sound pick-up state of a sound carried by a speech signal to be transmitted if the communication mode is the transmission mode; a control step of controlling the light-emitting device so that the light-emitting device is turned off, turned on or repeatedly turned on and off based on determination results of the communication-mode determination step and the sound pick-up state determination step; a speech-quality evaluation step of evaluating speech quality of the speech signal to be transmitted, wherein, in the sound pick-up state determination step, the sound pick-up state of the sound carried by the speech signal to be transmitted is determined if the communication mode is the transmission mode based on the speech quality of the speech signal evaluated by the speech-quality evaluation step; and a speech-segment determination step of determining whether or not the speech signal to be transmitted is a speech segment if the communication mode is the transmission mode, wherein, in the sound pick-up state determination step, the sound pick-up state of the sound carried by the speech signal to be transmitted, if the communication mode is the transmission mode, is determined based on a determination result of the speech-segment determination step and an evaluation result of the speech-quality evaluation step.
