Use pirate lingo. Sounding like a pirate isn't as hard as it seems! There are lots of resources for picking up pirate "lingo," so make use of them (some common terms listed below) in addition to trying to affect a vocal sound.
Gesture with your hands frequently. Don't forget that pirates do most of their talking on the deck of a ship - out on the ocean, where wind, waves, and bird calls make it tough to hear. Gesturing often gives you a sense of "being there.
Slur your words together. Saying, "The boys and I were out for a lovely day on the water today" sounds like something you'd overhear at a yacht club, not out on the bounding main! Instead, try, "Me 'n' these here scurvy scallywags drug our sorry keesters out t'th'ship'n'had us a grand great adventuaaarrr! We almost had t'keelhaul Mad Connie f'r gettin inter th' grog behind our backs!"
Use contractions whenever possible. Be sure to punctuate often with "Arrrr!"
Never use "you" or "you're" - ever.Never use "you" or "you're" - ever. Instead, use the piratical form, "yer", "ye" or "ya" for all forms of address to others. "Yer a scurvy bilge rat, ya pompous gasbag" or "Here's yer dinner, ya mangy cockroach." Note that you should always endeavor to call the addressee by some insulting name, usually involving an animal.
Embellish at will. A pirate is larger than life, and his or her speech should always reflect this. Don't just say, "We saw a whale off the starboard bow today." Say, "Me'n'th' crew seen a great grand sea beastie, th' mother of all whales, aye!"7Refer to yourself as "me" at all times, never "I." It is not piratically correct to say, "I have a cold." It is far better as a pirate to declare, "Got me a case o'th'sniffles, 'ass rye!"
More importantly, substitute "me" for "my" For example, don't say, "Look at my new sword," say "Lookit me new sword!." Also substitute "meself" for "myself" as in "Got meself a right fine ship!"
Mutter unintelligibly unless yelling. Being a pirate usually meant being liquored up to some degree - a lot of time, pirates were pretty mush-mouthed. In the step preceding, the term "'ass rye" actually translates to "that's right." Get it?
Be as loud as humanly possible. Pirates are not shy - stand tall, me hearties, and be counted!
Get a stuffed toy parrot and sew feet to right shoulder of a second hand store jacket. This will put you in the mood to adhere to the above mentioned rules and guarantee an abundance of "yers and arghs".
