Google has speech recognition services available for use from mobile phones (Android has it built in, iPhone users can use the Google application) - http://www.google.com/mobile/. We've found one article where someone tried to reverse engineer the service at http://waxy.org/2008/11/deconstructing_google_mobiles_voice_search_on_the_iphone/.
We want to better understand what is happening over the network when we use Android's RecognizerIntent. Does anyone have any experience using this service over the web or know of other articles that may explain its workings?
I read this presentation few weeks ago- http://www.abelski.com/courses/android/speechinput.pdf

Answer: just move your .apk file to your android phone it will work. Error is only occuring because we are trying to do in emulator
