Speech switching in speakerphone?
...to do
> here. If you find anything, I'm definitely interested.
The one idea I have is to have a default gain2 of 0dB and only when the
residual echo goes high we reduce the gain2. This could be implemented
similar to eq. (3) and (4) in this paper:
http://research.microsoft.com/pubs/69504/diegobenderskyhdres.pdf
The idea would be to use your estimation of the residual echo and noise
But to modify the calculation of the gain2. This would probably offer
a more robust solution since we do not have to rely on the SNR. However
we would lose the noise suppression functionality I guess (which probably
is...

My impression is that it does not make much difference on the timing to
set this parameter less aggressive. Depending on the how loud the
near end is talking it may detect double talk but most
