Replace Nuance Voice Commands with Google Voice Search

[longplaypg]

I would like to replace the Nuance Voice Commands with Google Voice Search when i press the call button on my bluetooth stereo headset.

I do not see a way to uninstall the Nuance Voice Commands...

I do not see a way to configure the phoe so that it uses Google Voice Search instead of Nuance Voice Commands...

Factory reset defaults the phone to Nuance Voice Commands...

I would like to press the call button on my stereo headset and have more voice commands than the Nuance app provides. Has anybody found a way to change this behavior without special access?

Sorry my phone is stock and no special access...
