Have you ever watched (heard) someone talking with the mic held between their lips/teeth - you can be a couple feet away from them and not hear them over the sound of the train/bus. It's actually pretty awesome.
Which is really annoying for the people sitting adjacent or across from them. Add more people speaking into their phones and the noise volume tends to go up.

I'd prefer my eyes over my ears and voice. Just imagine a train car full of people talking to their phones.

No, I don't think voice is a good choice either. But ears - I wear headphones all day already.
