how to pronounce "can't + d..." ?

t and d cannot be linked; they are both dental -labial sounds.

Press the tongue hard against the gum over your front teeth to pronounce 't', and at the same time flip the tongue loose from there to say 'd'.

You can only link a vowel sound and a consonant.

Eg: An + orange = ano...range. An apple = ana...pple.

No link. I can not deny.

Pronunce just like this: "ài quênt dêni".
