My apologies if this is unrealistic or has been previously mentioned, but this thread reminded me of a sensory replacement device I recently read about (I think it was in the New Yorker, or something). It uses light electric stimulation to map visual information to the tongue, and I think a blind man uses it to rock climb. On a conceptual level, it could offer an interesting way to supplement text-to-voice if the DF map info could be effectively sent through the device (say, transmitting a 3x3 grid to the tongue displaying walls, trees, etc. and using voice for detail). Seems like the price is around $10,000 USD though, so again, unrealistic.
