Hi,
You could of course modify the softwrae to pass (a
copy of) the voice to
the PC even in regular case. It's open source, after all ;)
Getting the DL voice audio can be done by just modifying the open-source part.
But for the UL voice (i.e. your speak), you might also need to patch
the DSP because AFAIR, there isn't any flag to get a copy of the
microphone audio.
Cheers,
Sylvain
