The voice that you use with customers/clients in the workplace. It's always amicable, with heavy use of upward inflections. The term was coined by Donnell Rawlings in his comedy act "From Ashy to Classy".
Say you work at a pizza place, and you're pissed off. Then a customer calls. Despite your anger, you will talk to that customer with an upward inflection, kiss their ass, and be almost overly friendly. The call ends. You've just utilized your corporate america voice. You can now go back to being grouchy, saying mean things about the customers who deserve it, and swearing profusely.
