VOICE COMMUNICATION DEVICE, VOICE COMMUNICATION SYSTEM, AND VOICE COMMUNICATION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a voice communication device, a voice communication system, and a voice communication method and program which, when performing half duplex communication by radio communication, can avoid collisions of upstream and downstream voice data in a limited bandwidth.;SOLUTION: The voice communication device is a device to perform half duplex communication by radio communication to and from a counter terminal. While voice data to be received from the counter terminal is being output from the local device, it enables voice data to be sent to the counter terminal to be input. And, during output from the local device of voice data to be received from the counter terminal, it keeps the input voice data saved in memory and, when it has finished receiving voice data from the counter terminal, sends to the counter terminal a request for control to ensure that voice data will not be transmitted from the counter terminal; thereafter, it transmits the saved voice data to the counter terminal.;COPYRIGHT: (C)2013,JPO&INPIT
