发明名称 VOICE COMMUNICATION CONFERENCE METHOD AND SYSTEM DEVICE
摘要 PROBLEM TO BE SOLVED: To provide the voice communication conference method and the system device in which acoustic characteristics of all connected places are freely corrected from one place integrally, centrally and remotely. SOLUTION: In the voice communication conference system device 9a where plural places A, B are connected by a voice line 1, each place A (B) has a measurement signal generator 4a (4b) and an acoustic characteristic measurement device 5a (5b). An acoustic characteristic controller 6 at the place A controls the devices 4a, 4b, 5a, 5b and the measurement result through the use of a control line 13 to correct the acoustic characteristic of all the points B and the transmission reception characteristic is measured by measuring the measurement signal generated at the point B or A by the other point A or B, and the acoustic characteristics of the entire voice communication conference system device 9a is automatically corrected by correcting the voice lines 1 of all the points based on the measurement result.
