enunciate (something) to (one)
To speak very clearly to one; to say something very precisely to one. Can you please stop mumbling and enunciate what you're saying to me? I can't understand you otherwise.
enunciate something to someone
to say something to someone very clearly and distinctly. Now, enunciate it to everyone, because they probably did not understand you the first time. I will enunciate it to you one more time, slowly.
