PURPOSE:To prevent head and end of words from being interrupted by applying a high frequency noise so that a transmission and reception level to a voltage comparator controlling an automatic loss adjusting device is equal to that at no talking period, in a voice remote conference system. CONSTITUTION:The transmission level and the reception level of each voice remote conference device are compared and a high frequency noise other than an audible frequency is applied normally to a noise generator 13 so that the transmission level and the reception level to the voltage comparator 11 controlling automatic loss adjusting devices 4, 6 at the transmission side and reception side are made equal to those at no talking period. Thus, since the loss of the automatic loss adjusting devices 4, 6 of each voice remote conference device at no talking period is small, no interruption of head of words is produced. Further, since the loss of the automatic loss adjusting devices 4, 6 is not increased until the voice in talking is lost, no interruption to the end of word is produced. |
