Marshmallow users : is voice dialer still alive ?

Hi,

I'm interested in the Marshmallow update for Nexus 6. I don't own a Nexus 6 so that's why I'm asking this question to you guys : when you long press the button of your wired headset while your screen is off and locked, does it still launch the ugly Voice Dialer or has it finally been replaced by Google Voice Search/Now ?

Because the Voice Dialer feature on my Galaxy S5 is just driving me nuts :silly:

Thanks !
