PROBLEM TO BE SOLVED: To attain proper voice delay control in matching with a display image by preventing intermission of a voice signal on its way to eliminate a sense of incongruity in an interactive state between a transmitter side and a receiver side. SOLUTION: A silence state detection section 4 of a voice delay controller 1 detects a silence state or a small sound volume state of a transmission voice signal, a silence state detection section 5 detects a silence state or a small sound volume state of a equipment voice signal. An interactive state detection section 7 detects both interactive states between a transmitter side and a receiver side based on the silence state detection signals from the silence state detection sections 4, 5. A camera position detection section 6 detects whether or not a television camera is in a state of being directed lower than a prescribed angle. A delay control timing control section 3 generates a delay on/off control signal with respect to the voice signal based on output signals from the silence state detection section 4, the camera position detection section 6, and the interactive state detection section 7 to control the operation of the voice delay circuit 2. |
