I haven't been able to find anything on this with a search, so I'm hoping someone might have an answer.
I have a Rocketfish bluetooth speakerphone in my car. When I press the button on the device to make a call, it automatically brings up something called Google Voice Dialer, which looks like this:
Apart from the voice itself, which is harsh ("SPEAK NOW!"), it usually gets the command wrong -- if it hears it at all. I'd really like to use the Google Now voice search, which is more accurate and less obnoxious-sounding, but I can't figure out how to make it the default. Any suggestions?
