Do we really need a bunch of people walking around talking to their phones without even having someone on the other end?
Actually, walking down the street is the speech-to-text situation for me. Sending a quick text or Gtalk reply with voice is a hell of a lot easier and safer than trying to pound one out when I'm in the crosswalk.
Did you pretend like you were talking to a real person? I could see the conversational style that Siri supports breaking down some of the awkwardness of this.
I would feel less awkward saying "Hey Siri, what's the weather going to be like tomorrow?" into my phone than "WEATHER. TOMORROW."
Yeah, it's a weird issue. It sort of depends on the context, but I think I would feel silly/awkward either way, but for different reasons.
If I'm at home, I feel less silly giving commands like "WEATHER. TOMORROW." I guess because I don't want to feel like I'm talking to something that's not human as if it's human? I'm not sure.
If I'm out and about, I want to use natural conversation so I don't look like an idiot, but would still feel internally strange, I guess for the reason above.
It may just be a matter of socializing the behavior enough for it to be acceptable. Maybe I won't feel as weird if everyone does it all the time.
