I took one of Barbossa's monologues from the first Pirates of the Caribbean movie and kinda just gave it a pirate accent. I was in no way at all trying to mimic Barbossa's voice.

I got the script here: https://www.actorama.com/ms/713/Ted-Elliot-and-Terry-Rossio/Pirates-of-the-Caribbean:-The-Curse-of-the-Black-Pearl

The background track is "Oceanside Campfire by Atmosphere ASMR" and can be purchased here: https://music.apple.com/us/album/relaxing-nature-sounds-deluxe-edition-rain-thunder/1073350931
