We don't really do anything with the VAD -- we just enable the module in the hope that the AEC algorithm itself will use the information. You might not be able to use the duck/cork modules directly, but you could potentially implement something like it in module-echo-cancel (the code for those modules is actually factored out into a stream-interaction.c file, so there might be some easy-to-use bits there).
