<p>PURPOSE:To prevent the malfunction of a controller by providing a voice controller for inputting voices information to a mobile station of radio equipment, and controlling the input level in response to the voice volume of a worker or the ambient noise level. CONSTITUTION:A worker speaks the prescribed information to a mike 33 after controlling the input level by an input voice volume controller 38. Then the voice of the worker is sent to a transmitter 31 via the controller 38 and converted into voltage signals. These signals are sent to a fixed station 20 for radio equipment in the form of rado waves through an antenna 34. The processing result obtained at the station 20 is delivered through a voice output device 13 and received by a mobile station 30 to be transmitted to the worker through a speaker 35. In this case, the voice input level is set at a high value together with increase of sensitivity in case the sound level is low at the periphery where the voices are inputted. As a result, the worker can feed the voice information at a low level. Thus it is possible to feed assuredly the voice information regardless of the level of the peripheral noise.</p> |
