A degree in audio engineering.
It's possible and there has been plenty of research done into it, but it's a hard problem and not just a question of slapping an off-the-shelf EQ on it.
I think you could probably get a close approximation by first close miking your recording, and then using Adobe audition, apply the dereverb filter to your recording, roll off the highs probably above 6 to 8000 Hertz or so by 12-18 db, and boost the fundamental frequencies and 1st overtone that the speaking voice is recorded in probably six decibels or so, (a rough guess would be something like 120 hz and 240 hz for men and 200 hz and 400 hz for women, use the spectral graph to find for sure), and then put a compressor on the whole thing to limit the difference between the loudest and quietest pitch to somewhere around 70 decibels or so, and then finally put a very light reverb with a lot of damping on it. We're talking almost so little reverb that you can't even tell that there is reverb applied to it unless you a/b the sound.
Things like that should account for the difference in bone conduction, the difference in how a microphone will pick up your voice and the rest of the room, etc., But it will probably need a lot of tweaking to your specific application to sound exactly right.
