Abstract
The used condition of a simplex communication apparatus is notified with a light-emitting device attached to the communication apparatus. It is determined whether a communication mode of the simplex communication apparatus is a transmission mode or a standby mode. A sound pick-up state of a sound carried by a speech signal to be transmitted is determined if the communication mode is the transmission mode. The light-emitting device is controlled so that it is turned off, turned on or repeatedly turned on and off based on determination results of the communication-mode determination and the sound pick-up state determination.

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.
A communication apparatus comprising:
- a first pick-up unit configured to pick up a voice sound;
- a transmitter unit configured to transmit the voice sound picked up by the first pick-up unit to outside as a first speech signal;
- a communication-mode switching unit configured to switch a communication mode between a standby mode in which the transmitter unit does not transmit the speech signal and a transmission mode in which the transmitter unit transmits the speech signal;
- a sound pick-up state determination unit configured to determine a pick-up state of the voice sound picked up by the first pick-up unit;
- a light emission device configured to emit light;
- a control unit configured to control the light-emitting device so that the light-emitting device is turned off, turned on or repeatedly turned on and off based on the communication mode switched by the communication-mode switching unit, and the pick-up state of the voice sound picked up by the first pick-up unit and determined by the sound pick-up state determination unit;
- a speech-quality evaluation unit configured to evaluate speech quality of the first speech signal to be transmitted by the transmitter unit, wherein the sound pick-up state determination unit determines the sound pick-up state of the voice sound picked up by the first sound pick-up unit based on the speech quality of the speech signal evaluated by the speech-quality evaluation unit;
- and
- a speech-segment determination unit configured to determine whether or not the first speech signal to be transmitted by the transmitter unit is a speech segment, wherein, the sound pick-up state determination unit determines the sound pick-up state of the sound to be transmitted as the first speech signal based on a determination result at the speech-segment determination unit and an evaluation result at the speech-quality evaluation unit.
