Tsuwm has it just about perfect. And the note about enunciating is spot on!

I find it annoying that some machine voices do not take into consideration that you may have a phone with the dial buttons IN the handset ... so have to take the handset away from your ear to punch a number and in the two seconds it takes to get the handset back to your ear the NEXT instruction is half done! Arrrrggghhh.
No way to fix that, I guess. Can't imagine they haven't thought of that circumstance and failed to correct it.
I know that the answer is for caller to use a set with the buttons on a separate unit of the telephone. But not always possible ... friend's home...hotel...
wow
