Word/Phoneme Corpus for an Elman SRN (English)

Question

I'm writing an Elman Simple Recurrent Network. I want to give it sequences of words, where each word is a sequence of phonemes, and I want a lot of training and test data.

So, what I need is a corpus of English words, together with the phonemes they're made up of, written as something like ARPAbet or SAMPA. British English would be nice but is not essential so long as I know what I'm dealing with. Any suggestions?

I do not currently have the time or the inclination to code something that derives the phonemes a word is comprised of from spoken or written data so please don't propose that.

Note: I'm aware of the CMU Pronouncing Dictionary, but it claims it's only based on the ARPABet symbol set - anyone know if there are actually any differences and if so what they are? (If there aren't any then I could just use that...)

EDIT: CMUPD 0.7a Symbol list - vowels may have lexical stress, and there are variants (of ARPABET standard symbols) indicating this.

Answer 1

CMUdict should be fine. "Arpabet symbol set" just means Arpabet. If there are any minor differences, they should be explained in the CMUdict documentation.

If you need data that's closer to real life than stringing together dictionary pronunciations of individual words, look for phonetically transcribed corpora, e.g., TIMIT.
