You mention "duplicate words", but you have removed duplicate characters in your expected output.
So I shall assume you want to remove duplicate characters, and not words.

Code:
$
$ cat f2
i love google
i love yahoo
i am tech savvy
$
$ perl -lne 's/(.)\1//g; print' f2
i love ggle
i love yah
i am tech say
$
$
