Corpus/data set of English words with syllabic stress information?

I know this is a long shot, but does anyone know of a dataset of English words that has stress information by syllable? Something as simple as the following would be fantastic:

AARD vark
A ble
a BOUT
ac COUNT
AC id
ad DIC tion
ad VERT ise ment
...

Thanks in advance!

From stackoverflow

• I closest thing I'm aware of is the CMU Pronouncing Dictionary. I don't think it explicitly marks the stressed syllable, but it should be a start.

  dmcer : I would add that it does actually mark primary and secondary lexical stress. See the 1s and 0s on the phones here https://cmusphinx.svn.sourceforge.net/svnroot/cmusphinx/trunk/cmudict/cmudict.0.7a .

  endtime : Thanks guys, that's perfect.
