Comparing words with the words in dictionary and getting the corresponding values?

[dechen]

How do I compare words of sentences with a dictionary and get it's corresponding value.

e.g, This is the dictionary format.

WORD Pronunciation

try t-r-y-0|
test t-e-s-t-0|

Sentence list:
I try my best.
The knowledge test.

So for each word in the sentence must do dictionary lookup and get the it's corresponding values (i.e, pronunciation) and print them sentence wise. I would be grateful for the help.

...     v = dd.get(word, None)

t-r-y-0|
