english dictionary API with phonetics and accents?

Question

I'm not only a programmer, but an amateur poet, and I'd like to build some custom rhyming dictionary programs. I want to be able to specify what kinds of rhymes and follow patterns on the rhythm of words (iambic vs trochaic) as well as the sound.

So, is there an API, dictionary DB essentially for english that has the spelling of words as well as the phonetics and accents? Basically I need whatever a rhyming dictionary program would use, a good one. Any format: a database, XML, something.

This is a hard question to answer with google so I am asking here.

I found this web based dictionary:

That page explains how he made the dictionary.
