字母t在詞尾的發音

Hi,
其他字母在詞尾時也會被顎音化嗎？
Some letters in front of some words are palatalized as well.
It is usually allophonic and it may go unnoticed by native English speakers. As an example, compare the /k/ of English key with the /k/ of coo, or the /t/ of tea with the /t/ of took. The first word of each pair is palatalized, but few English speakers would perceive them as distinct.
I think the s sound may fall into this group too.

t/(the voiceless sound) makes a bigger puff of air. Try to put your hand in front of your mouth and make the /t/ sound, you will feel the big puff of air.

The consonant sounds in "did" and "ted" are both made by putting our tongue right behind our top teeth and then moving it to release a small puff of air.
