For the ones thinking this is great, have you actually tried to talk without making sounds?

I don't think it is an intuitive action at all and I became self-conscious about not making a sound rather than talking like I normally would.

I suppose it would require some "getting used to."

Regardless, I think it is a cool idea and a real problem. Sometimes I don't want to type nor talk out loud so I find myself whispering at my phone like I'm telling it a dirty secret.
