Abstract
For use in multiport digital conference arrangements wherein the speech samples of selected speakers are included in an output sample for distribution to the conferees, the disclosed arrangement features a speech detector for each port and processor-controlled switching hardware. By evaluating the conferee's speech level, the current state of the port, and other factors, each conferee is dynamically assigned an adjusted priority by a conference processing program. The speech samples of only the highest priority conferees are summed to control noise level, singing caused by echo, and other types of distortion.
