Many English teachers are far too conservative and do not address English pronunciation word reductions. Various types of pronunciation are now acceptable within certain words because they make pronunciation in conversation easier.
If you are an English learner, you probably pronounce each word as clearly and fully as you are able — but native English speakers do not do this, which might mean you have a difficult time occasionally understanding what a native English speaker has said.
Natural spoken English contains what are called reductions — a sound that has changed or disappeared when spoke at normal speaking speed.
Practice speaking with reductions will help you speak more naturally and more like a native English speaker.
In addition to reductions, native English speakers will often “attach” words to the end of previous words.
Actual: We made a mess Spoken: We ‘mada’ mess.
Actual: I wrote a check. Spoken: I ‘wrota’ check.
Many native English speakers will reduce the word, ‘you,’ to simply ‘ya’
Are ya hungry?
Where are ya?
The word 'and' often gets reduced to N in spoken English
Friends n family
Apples n bananas
