RECORDER AND REPRODUCER FOR AUDIO CONFERENCE

摘要

PURPOSE: To compress the quantity of recorded data on an audio conference and to reproduce these recorded data with high efficiency. CONSTITUTION: The file data quantity can be reduced when the silent parts included in the ordinary conversations are not recorded. A voice part detector 105 and a file producer 106 perform the processing to reduce the silent parts. In a reproduction mode, the voices of only a designated person can be recorded among all participants of an audio teleconference based on the participant information added to every unit voice signal. Furthermore, only the voice parts and the real time including the silent parts can be reproduced. The time information is used when the synchronization is secured among voice signals divided at every unit time and only the voice signals of the corresponding paritipant are selected based on the participant information.
