I thought Siri was supposed to learn your voice for the Hey Siri feature? Or was that just an iPhone thing? The reason I ask is because I bought my wife an Apple Watch since I liked mine so much, and while I was showing her some features I used Hey Siri, and her watch responded along with mine, and it picked up every word. I was also about 8 feet away from her. Does this happen to anyone else? Is there a way to fix it? I'm not sure how much of a problem it will be in everyday use, but I found it a little odd.
