Quick warning to not play the video in the room with an Echo. Now I have Alexa telling everyone in the house that green hippo is hungry!!

Which begs the question, how do they broadcast "Alexa, ..." on TV shows so that it doesn't set my Echo off?

This is from 2018, but presumably they use largely the same method now: https://www.theverge.com/2018/2/2/16965484/amazon-alexa-supe...

To save a click:

> Apparently, the Alexa commercials are intentionally muted in the 3,000Hz to 6,000Hz range of the audio spectrum, which apparently tips off the system that the “Alexa” phrase being spoken isn’t in fact a real command and should be ignored.
