I found this site has recordings of people within the State of North Carolina
North Carolina number nine sounds alot like how Andy griffith talks and is eastern but none of the recordings sound like Senator Edwards or Governor Easley who both are eastern North carolina former residents but both have strong dialects.
I thought it was interesting I couldnt pick up on the winston salem dialect in the recordings and I assume that is because I grew up close to that city.
The outer banks male was a hoot and lol I know quite a few people who have that type of dialect .
They left off the foothills in my opinion has a very deep dialect.
I thought I share for you to enjoy
