Two Googles in a room...
Voice-activated smart products are coming at such a rate that we soon began wondering what would happen when we had two or more of them in the same space. Here we had the opportunity to try, with the JBL Link 10 sat right next to the Google Home, sharing the same power point, the same Wi-Fi. You can’t change the key word for a Google device — it’s ‘Hey Google’ or ‘OK Google’, and you can’t change it to ‘Hey JBL’, so there’s no way to talk to one with also addressing the other*.
Will they both reply in unison? No they won’t. Somewhere between your key word, the sending of your speech overseas to Google’s computing farms and the delivery of the generated reply, Google has noted the duplication of devices and eradicated it. Which one gets to reply? In our situation it was the Google Home every time at first; the JBL showed it was receiving the command, but did nothing unless we specified it as a target for music. But then later it switched, and the Link took over. Last one used? No. Nearest? Apparently yes, if you’re much closer to one than the other. Google, it seems, may license out its Voice Assistant, but given a conflict, it doesn’t insist on winning.
