As Jock Scot, JSFMACLJR and others have pointed out, there is no such thing as a standard Scottish accent. Some parts of the Highlands and Islands speak better English than the English as it is, to them, a second language and many Scots are educated south of the border. The south and the north-east have problems understanding each other and nobody understands Glaswegians! My own accent is Glaswegian, tempered by Dumfries, modified by Ayrshire and turned on its head by 22 years in the British Army!
