Non-dev comment.

I very very rarely ever use voice recognition, and never use dictation. I only use it on rare occasion when I can't remember how to spell a word, and my best guess has spell check all confused. Plus with all the NSA and other privacy issues coming up, I'm working harder than ever to keep and and all unnecessary data out of "the cloud”. 

These privacy issues are why a year and a half ago, I completely stopped all usage of GPS navigation the requires any kind of data connection. Printing directions is one thing, but having a server track and direct you movements all the way to your destination, is unacceptable in this day and age.

I would use voice recognition, dictation, ect on a Ubuntu Touch device if I knew for sure all processing was done locally, I.e. on the device itself. Same goes for GPS nav. 

God Bless all your guy's/gal's work.
