<p>PURPOSE:To transmit accurately output content even to a person at a location subject to surrounding noise by providing a delay circuit section, an input voice coding section, a comparator section and a discriminating section so as to attain a broadcast output again. CONSTITUTION:An input voice from a microphone 16 is amplified by a voice receiver 14 and inputted to an input voice coding section 12. After the coding section 12 codes an input voice, the result is given to a comparison section 10. The comparison section 10 compares a coded voice signal inputted from a delay circuit section 9 with a coded voice signal inputted from the input voice coding section 12 for the level difference and discriminates whether or not it is within a set range. The result is fed to a discriminating circuit section 7, which transmits a re-broadcast command top a message editing control section 2 when it is informed that the level difference is not within the set range. Thus, the re-broadcast is executed automatically and the output content is transmitted accurately even to a person at a location subject to surrounding noise.</p> |
