How to Talk With a New York Accent. The language spoken by many New Yorkers is distinct both because of the accent used and because of certain phrases are uniquely "New York." Learn how to talk with a New York accent.
Understand the pronounciation of certain words. In a New York accent, the "r" at the end of a word is almost never pronounced. The "g" at the end of a word isn't pronounced either. So "going" is pronounced "goin'" and "here" sounds like "hea". The "th" sound sounds something between "d" and "th", but if you're unsure, speak with the "d" sound.
Know that many of the words that have the "o" sound (like in coffee, dog, talk) are pronounced with an "aw" sound, so the word dog, for example, would sound like "dawg", as well as "coffee." The "aw" sound tends to replace the "o" in all words spoken with a thick New York accent.
Know that the traditional New York accent is like a strong and rough, often with a deep sounding voice. Words are spoken kind of in a relaxed way. Since New York was at one point very Italian, Staten Island and Brooklyn in particular, people of Italian descent that live in the areas tend to have a little bit of Italian accent mixed in. Familiarity with an Italian accent may make the process easier for you.
Have an attitude. Speaking like a New Yorker is less about what you say, and more about how you say it. New Yorkers are known for being direct, opinionated and confident. They are also known for talking a lot, and talking loudly.
Look to American television and popular movies to listen to this accent. The Sopranos series, and any gangster movies, such as The Godfather, are filled with the NY lingo.
