However, I also get the same problem with the 2011.20 files. Can you give me any tips? Did you perhaps use the mapsource install for 2011.20? I used the unlocked IMG file and the ASR files from the 2011.20 post. I can only get full voice by going back to my old version.
I tried the 2011.20 mapsource, and this failed as well as far as the ASR files go. I am guessing that the only way to get voice recognition to work on nuvi 8xx at this point is to use the "full install" -- and the only version of this I have is 2010.30.
