The pronunciation of the letter T is usually dropped and replaced with a glottal stop when the sound is at the end of a word. Hard consonants are usually dropped in general and word pronunciation is very vowel heavy.

When saying you are doing something the "ing" is pronounced more as an "in'"

There's lots more such as slang but that's learnt over time if you live here and the slang is very localized.
