I don't think there is a way, the fault is on Google now and not touchless controls. I was a little bummed about this to, with my sgs3 I was able to send texts through voice command and say "send"... Though, vice command was pretty useless on it, if I wanted to text anything longer than 4 words it would take me 10 tries to get it right... At least with the moto x, it gets it deadnuts 99% of the time. For now, I'll take the trade off of having to do one click and it actually working. Hopefully some day it will work the exact way that we want it... Until then, I am content.
