Apple posted this series of videos over the weekend. All three are about a minute long and, if you’ve got a HomePod or one in your future, they’re worth watching.
Side note, as part of walking you through the specifics of how to use Siri with HomePod, this first video says “Hey Siri”, followed by a command. Being my inquisitive self, I replayed the video a few times sitting in a room with my HomePod, just to see what would happen.
Sure enough, my HomePod picked up on the commands, though not nearly as cleanly as if I spoke the same words. I know that the Amazon Echo filters out some Alexa occurrences. I wonder if Apple does something similar, or if the voice quality coming out of my MacBook Pro speakers is not nearly as clear as my voice.
