How can I disable Google Voice Commands on an Android phone?
Here's how you can turn this off in most Android builds:

Look for an app called "Google Settings." By default, the icon will look like this:



From there, choose "Search &amp; Now" &rarr; "Voice" &rarr; "'Ok Google' hotword detection" and turn that setting off.

If that doesn't apply to your phone's OS, you'll need to provide more info. If you are running the OS that came with the phone, provide the make and model. If it is rooted, provide the name and version of the custom ROM.
