I have heard from several people over the past year saying Siri starts talking all on her own at odd times.
At 3:33 am today, and yes, it really was 3:33 am when I looked at the phone, Siri woke me up saying something I didn't quite catch. At first I thought it was my daughter talking in her sleep, but it wasn't, it wasn't her voice, it was definitly Siri's voice (male with Aussie accent); then I thought maybe I was dreaming it, but nope, not that either, because when I asked Siri to repeat what he said, he said, "I don't know the answer to that question Jill, but here are some links that might help you", and the phone showed 3 web links below about crawfish! So, then I thought maybe it was ME talking in my sleep. However, I don't recall dreaming about crawfish; honestly though, I don't remember what I was dreaming about, maybe I was eating, cooking, or ordering Creole food? I could've been, I suppose.
It's really very funny, but also disconserting at times, such as when it wakes me in the wee morning hours about something I didn't even know I was dreaming about. Could be downright spooky too. I'm now convinced Siri is schizophrenic. 😁😁😁
