The letter t only exists when I'm typing.

For example, bow and boat sound similar when I say them, except that the o sound in boat will end abruptly whereas bow carries it on a little.

Also, the phrase "who's he when he's not at home?". The only word that is pronounced as it is spelled is "when". For me, it's "'oo's 'e when 'e's no' a' ome?". xD
