[Speex-dev] near and talk suppressed

I have a question about the AEC and preprocessor.

I have seen that when near end is talking for a longer time (about 10 s) without being interrupted
by the far end the residual echo (or rather leak_estimate) increases making the preprocessor
suppress the near end talk when it shouldn't.

Is there a way to make the leakage estimate only update when far-end is present or similar
in order to avoid this behavior?

If I need to implement this myself, does it make sense to put some kind of far_end threshold
on the update of leak_estimate or should I rather pause the adaption or do something else?

Best Regards
