Marshmallow question: is texting entirely by voice now possible?

I heard in Google's press announcment today that they improve the voice actions in 6.0. For those who have been using the marshmallow DP on their devices can you answer a question for me.

With Google now if you say "text <contact name>" it will prompt you to say your message. But then after you speak your message it asks you to look at the screen and verify that it is correct before sending. This is obviously not a completely hands free operation which you would need while driving, biking, running, etc.

I was just wondering if they had improved this at all?

Thanks!
