When people say they love British accent, most would probably be thinking about Received Pronunciation (also known as the "Queen's English"), or BBC English. It's the typical southern accent that most people hear through media. However, there are many accents in Britain. Here are three examples of other British accents.

Cockney accent is commonly  found in London, notably East End, hence the show "Eastenders". Cockney accent has a few interesting features:

1. T-glottalisation:  For words that have /t/  or /k/ in the middle of the word, people make a glottal stop [ʔ] instead of enunciating [t] or [k]. For example, better /'bɛtə/ becomes /bɛʔə/. 

2. Th-fronting: /θ/ becomes [f] in all environments. For example, "three"          /θrɪː/  becomes /frɪː/. /ð/ becomes [v] in all environments as well, such as "brother" /ˈbrɒðə/ becomes /ˈbrɒvə/.

3. Vocalisation of dark L:  The /l/ is realised to [u], [ʊ], [o] or [ɤ]. For example, the word "milk" /mɪlk/ becomes /mɪʊk/

Birmingham is one of the largest cities in Britain, only second to London. It is also described to be an accent that is very hard to mimc. https://www.bbc.com/news/magazine-29307916 

Here are some features of Birmingham accent:

1. Absence of Foot-Strut Split: Both the word "foot" and "strut" have the same vowel pronunciation, which is [ʊ]. This is the same as with Northern England, though Birmingham considered to be Midlands.

2. Price-Choice Merge: Both the word "price" and "choice" have their vowel sound merged into [ɒɪ].

3. Letter ng: While most parts of England pronounce words such as "singer" with /ŋ/, without a distinct [g]. Birmingham speakers pronounce [g] so it becomes /ŋɡ/.

Scouse Accent, or sometimes called Liverpool English, is usually found in Liverpool and it is very distinct and different from the rest of England. 

Here are some features of the accent:

1. Absence of Trap-Bath Split: Both "trap" and "bath" are pronounced with the same vowel sound [a] .

2. Square-Nurse merge: The word "square", instead of having the vowel pronunciation [eə], the vowel [ɛː] is used, just like in the word "nurse". This is different from most British accents.

3. G-dropping: For words that ends with "ing", like "saying" or "singing", the [ɪŋ] is replaced by [ən].
