About the CMU dictionary

The Carnegie Mellon University Pronouncing Dictionary is a machine-readable pronunciation dictionary for North American English that contains over 125,000 words and their transcriptions.

This format is particularly useful for speech recognition and synthesis, as it has mappings from words to their pronunciations in the given phoneme set. The current phoneme set contains 39 phonemes, for which the vowels may carry lexical stress.

Note that this dictionary is not in the format you want to use for the Sphinx decoder. For that purpose, use the following tool.
