Neil Patrick Harris shows off 'Hey Siri' in Apple's latest iPhone 6s ad

In the new 30-second ad, Harris prompts his phone to read a saved memo from the Notes app using only his voice. Siri responds accordingly, allowing Harris to freshen up his tuxedo and practice the speech without touching the iPhone 6s.

The ad ends with a joke regarding the robotic nature of Siri's voice, as Harris tells the mirror he'll "be a lot more natural."

Harris was the one handing out an award in the last iPhone 6s ad, which focused on the high-resolution 4K camera and its filmmaking capabilities.

Apple has mostly chosen to focus on individual iPhone 6s features in ads for its latest-generation smartphone. The company previously spotlighted handsfree "Hey Siri" capabilities in an ad that featured a very different type of celebrity than Harris —  Sesame Street's Cookie Monster.
