Alexa and Siri can hear commands that we can't

Sounds like Alexa and Siri are more in the know than us humans.

Researchers have found that they can insert hidden commands into other audio pieces that humans can’t hear because of the high frequencies…but Alexa and Siri can.

From the sound of things (or lack thereof), my ears are older than me. I can’t hear the 15,000 Hz.
