Many English words with 'ct' at the end, in the phonetics symbol it writes as kt, I was wondering if we REALLY need to pronounce the k sound in daily life, cos when I watch native speakers speak the following words, they seem just to pronounce as contact ˈkɒn tŠt,perfect pə ˈfet,object ˈɒb dʒet without k sound but in dictionaries which indicate us to pronounce contact ˈkɒn tŠkt, perfect pə ˈfekt,object ˈɒb dʒekt with k sound, please advise. Thanks
This also happens with the /pt/ of "concept, contempt", etc. where the bilabial plosive /p/ is not released until the /t/ is.
So you should not consider it something you can skip over.
There are dialects where the end of the consonant cluster is dropped. This is non-standard. The spelling 'perfick' is a common 'eye-dialect' rendition of this tendency.
But if you've ever taught Asian students you might have noticed they have trouble believing we pronounce final consonants so faithfully, and often assume they can be skipped or at least devoiced. "Do you eat crap?" asked one colleague at a seafood restaurant.
