Echo cancellation method, device and computer-readable storage medium

A device comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors, the memory storing programs that, when executed by the one or more processors, cause performance of operations comprising:
• acquiring a reference-aligned signal and a microphone-aligned signal;
• filtering the reference-aligned signal and the microphone-aligned signal by using a preset adaptive filter to obtain a filter output signal;
• performing speech compensation processing on the filter output signal according to the reference-aligned signal and the microphone-aligned signal to obtain a compensated speech signal;
• and
• performing nonlinear processing on the compensated speech signal to obtain an echo-cancelled speech signal.

A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor of an electronic device, cause the at least one processor to perform an echo cancellation method, the method comprising:

• acquiring a reference-aligned signal and a microphone-aligned signal;
• filtering the reference-aligned signal and the microphone-aligned signal by using a preset adaptive filter to obtain a filter output signal;
• performing speech compensation processing on the filter output signal according to the reference-aligned signal and the microphone-aligned signal to obtain a compensated speech signal;
• and
• performing nonlinear processing on the compensated speech signal to obtain an echo-cancelled speech signal.
