Not so far as I'm aware, but you could probably make a good case for Sarah Gardner learning Ancient, either during her time as Osiris' host, or after that fact. There's also Lieutenant Satterfield (played by Grace Park), should you decide that you can use a military officer instead. She speaks and reads some Goa'uld; it's a perfectly reasonable conclusion that she'd try to learn Ancient as well since it would likely come in useful more and more over the years.
