SYSTEMS AND METHODS FOR DOUBLE-TALK DETECTION IN ACOUSTICALLY HARSH ENVIRONMENTS |
摘要 |
A communications device that is configured to detect double talk is described. An echo canceller is configured to cancel an echo from an input signal using an adaptive filter. A double-talk detector provides a double-talk statistic. The double-talk statistic is proportional to the ratio of the remaining echo energy in the cancellation error signal and the total cancellation error energy. |
