Claim 10:
11. The method as claimed in claim 10, further comprising:
in response to determining that a signal level of the microphone is lower than or equal to a threshold, determining that a second status of the microphone is that the microphone is muted; and
in response to determining that the signal level of the microphone is higher than the threshold, performing the following steps:
determining that the second status of the microphone is that the microphone is working normally;
sending a second status signal indicating the second status of the microphone to the far end through the cloud network;
obtaining the filter coefficients from the AEC adaptive filter; and
calculating similarity between the obtained filter coefficients and the reference filter coefficients.
