I'm developing an Android voice recognition app using RecognizerIntent. The client is concerned with data being transmitted between device and Google's speech recognition server and whether it can be intercepted.
I found very little documentation on what format and how the data is being sent back and forth.
Does anyone know where I can find this information? Is communication between the device and Google speech recognition encrypted/secure in any way?
See Google's voice search speech recognition service which may be helpful. And, of course, the now famous http://mikepultz.com/2011/03/accessing-google-speech-api-chrome-11/ which shows the workings of the Google Speech recognition in the Chrome Browser.
