I grew up in Augusta, the son of a father from Houlton and a mother from Rockland. When it comes to being a dyed-in-the-wool native with a pedigree of potato pickin' and lobsterin' the accent around my house was a beautiful mix or North and South. The Maine Accent is fairly similar where ever you visit and is always served best by the old timahs.  I just came across a video of a wicked Mainah tellin' stories on the porch from his rockin chair in Jonesport. I could listen to this fella all day long. Love it! If you wanna learn how to sound like traditional speakin' Yankee, imitate this guy. His "Ayuh" is the most authentic one around. Now and then, mutha's voice pops in too.
