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

Question

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
...

Answer 1

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.
