During the Christmas holidays you might talk to local people in and around Norwich. As you will have noticed, the local accent is a bit different from the “standard” English of the BBC or most of your teachers.
The word here sounds like hair;beer sounds like bear;really sounds like rarely.
The -y- sound before the vowel in words like music is omitted, so Hugh sounds like who;feud sounds like food. (This is called yod-dropping.)
Older people may pronounce words like home, stone, boat with the same vowel sound as foot or put.
There are also some differences in grammar and vocabulary.
