Turn the Volume Down

Anyone know how to teach a 2 year old to use a quiet(er) voice? He practically yells everything he says... We were at Kyndi's Kyndi-garten assesment and I told the Littles they need to be quiet (and I provided them with Swedish Fish to assist in this...) They both did so good, until about 10 minutes in... then they were bored of sitting quietly. Oaks would whisper things to me so she was still very quiet. Dayton however was, well, Dayton. He is loud I tell you. And no amount of "Shh" or "Please talk quietly" was doing me any good. I'd whisper and ask him to whisper and he continued to yell his responses. Will I ever get a quiet voice out of him? My sources say no.
