I'd say it goes further than that, as this isn't 1992 any more. I can't possibly find code pronunciation to be of imperative importance because I rarely debug code over the phone.

At any given time, I'm likely to have at least two of the following with me: a phone, a tablet or a laptop. Just e-mail me the code. Make a gist with the problematic section. Push it to a branch in our git repo so I can take a look at it myself. IM it to me. Don't read it to me.
