About the CMU dictionary

The Carnegie Mellon University Pronouncing Dictionary is an open-source machine-readable pronunciation dictionary for North American English that contains over 134,000 words and their pronunciations. CMUdict is being actively maintained and expanded. We are open to suggestions, corrections and other input.

Its entries are particularly useful for speech recognition and synthesis, as it has mappings from words to their pronunciations in the ARPAbet phoneme set, a standard for English pronunciation. The current phoneme set contains 39 phonemes, vowels carry a lexical stress marker:

0

1

2

Bear in mind that this is a dictionary. If your word is not in the dictionary (or was misspelled) nothing will be returned. This also applies to items such as numbers; you should spell out what you need. This tool will try to come up with pronunciations for words not in the dictionary. Please feel free to send word suggestions or point to errors inpronunciation. Bear in mind the language changes over time, in particular novel words may not be in the dictionary; you can make suggestions for ones that seem to be here gor a while.

Phoneme Set

The current phoneme set has 39 phonemes, not counting varia due to lexical stress. This phoneme (or more accurately, phone) set is based on the ARPAbet symbol set developed for speech recognition uses. You can find a description of the ARPAbet on Wikipedia, as well information on how it relates to the standard IPA symbol set. If you check off the stress box you will get a pronunciation in which vowels are annotated (see above). Stress is difficult to get right and people disagree about it. There are words in the language that differentiate by stress (e.g. PR'OGRESS PROGR'ESS).
