Neil Patrick Harris demonstrates one of the possibilities when you use the hands-free Siri feature on the iPhone 6s. Subtle string music backs up the tuxedo-wearing actor who stands in front of a mirror, brushing his suit off. "Hey Siri," he says, and he asks her to read a note from his phone. Using his brush as a mock microphone, Harris lip syncs along as Siri reads his thank you speech aloud. After thanking his parents and husband, he reminds his kids they should be asleep and then pauses for laughter, playing to the fake crowd. With one last brush of his suit, he assures himself in the mirror that he'll sound much more natural for the real deal.
