I think people don't speak at their phones simply because the experience is so horrible.
I would LOVE to be able to voice control the various aspects of my phone but it's so mind numbingly frustrating that I'm annoyed just thinking about it. If it was better I would sacrifice other features for it.
Totally agree, the second I have to switch from a normal voice to a stupid voice with the correct nuances for the unit to "work" is usually the last time I use it.
Our google home basically sits there all day waiting for my wife to say "play abba", she has a strong non-English accent and it's about the only thing it seems to pick up. Don't get me on cars where I have to say the exact sentence to do anything.
