We generated this dictionary using the following independent sources:
- a 20k+ general English dictionary, built by hand at Carnegie Mellon
  (extensively proofed and used).
- a 200k+ UCLA-proofed version of the shoup dictionary.
- a 32k subset of the Dragon dictionary.
- a 53k+ dictionary of proper names, synthesiser-generated, unproofed.
- a 200k dictionary generated with Orator, unproofed.
- a 200k dictionary generated with Mitalk, unproofed.

All entries that occur solely in copyrighted sources, like the Dragon
dictionary, are not currently included in this dictionary. If you have
words and transcriptions that you would like included in this unrestricted
resource, please send them to Robert L. Weide (weide@cs.cmu.edu) and we
will consider them for an upcoming version.

All of the above sources were preprocessed and the transcriptions in the
current cmudict.0.1 were selected from the transcriptions in the sources or
a combination thereof. We have removed some potentially unreliable
transcriptions from this dictionary, including those based on only one
source, and will reintroduce them once we have verified the transcriptions.

CMU does not guarantee the accuracy of this dictionary, nor its suitablity
for any specific purpose. In fact, we expect a number of errors, omissions
and inconsistencies to remain in the current result. We intend to
continually update the dictionary as we make progress in correcting them.
We will make subsequent versions available via anonymous ftp, and those
who would like notification when updated versions are available should
send email to weide@cs.cmu.edu.

We welcome input from users: send e-mail to Robert L. Weide
(weide@cs.cmu.edu) if you have comments and suggestions on the content
