ACOUSTIC ECHO PATH CHANGE DETECTION APPARATUS AND METHOD |
摘要 |
An acoustic echo path change detection apparatus constituted of: a time domain path change detection functionality arranged to: detect a change in a near-end acoustic echo path responsive to a time domain analysis of a near-end signal and a signal output by an acoustic echo canceller; and output an indication of the detected change, a frequency domain path change detection functionality arranged to: detect a change in the near-end acoustic echo path responsive to a frequency domain analysis of a far-end signal and the signal output by the acoustic echo canceller; and output an indication of the detected change, and a combination path change detection functionality arranged to: determine a first function of the output indication of the time domain path change detection functionality and the output indication of the frequency domain path change detection functionality; and output the determined first function. |
