AUDIO CONFERENCE PLATFORM WITH DYNAMIC SPEECH DETECTION THRESHOLD |
摘要 |
The present invention comprises a method for audio/video conferencing including an audio conferencing platform (26), the platform comprising network interface cards (38-40), processing boards (44-46), a CPU (48), a TDM bus (42) and a PCI bus (50). The method comprises using dynamic threshold value to determine whether there is speech on a line. In one aspect, the method comprises determining a dynamic threshold value based on one or more chracteristics of signals received on a port, associating that dynamic threshold value with the port; and comparing one or more characteristics of signals subsequently received on the port to the dynamic threshod value. Signals received over a plurality of ports are summed, but for ports whose signal characterisics have a specified relationship to the dynamic threshold value associated with that port, signals are not contained in the sum.
