It won't work on google phone right now, from the paper: "The audio adversarial examples we construct in this paper do not remain adversarial after being played over-the-air, and therefore present a limited real-world threat; however, just as the initial work on image-based adversarial examples did not consider the physical channel and only later was it shown to be possible, we believe further work will be able to produce audio adversarial examples that are effective over-the-air."

However prior work [1] was shown to work on google phones, it is just much more noticeable.
