The CMU Pronouncing Dictionary (also known as cmudict) is a public domain pronouncing dictionary created by Carnegie Mellon University (CMU). It defines a mapping from English words to their North American pronunciations, and is commonly used in speech processing applications such as the Festival Speech Synthesis System and the CMU Sphinx speech recognition system. The latest release is 0.7a, which contains 133,746 entries (from 123,442 baseforms).
Database Format
The database is distributed as a text file of the format word <two spaces> pronunciation. If there are multiple pronunciations available for a word, all subsequent entries are followed by an index in parentheses. The pronunciation is encoded using a modified form of the Arpabet system, with the addition of stress marks on vowels of levels 0, 1, and 2.
