I post here rather than in the Smartphone as I think the question is applicable to tablet Android as well. My goal here is to change the Voice Command application from the factory installed Voice Command to either the Google Voice Command or perhaps another application such as Hound. Reason is Voice Command does not work for making voice command telephone calls (including using the stored directory). Both Google and Hound if manually selected perform perfectly, Voice Command fails completely. Another problem, or complication, I want the change the default voice command so when I use a bluetooth speakerphone it will connect to my smart phone through Google or Hound voice command, not the Android voice command. I am unable to uninstall Voice Command or I'd try that.
