This describes the source of the cuvoald.scm file.

The Computer users version of Oxford Advanced Learners' Dictionary is
moade available without charge from the Oxford Text Archive.  Its
is available for non-commercial use only.

The file oald2ft.tar.gz contains the source of a program that
can convert the file available from the Oxford Text Archive
into Festival's lexicon format.

The original files may be ftp'ed from (please check their licence)
       ftp://ota.ox.ac.uk/pub/ota/public/dicts/710/

The resulting file was used to construct a letter to sound model
which is included in oald_lts_rules.scm and oald_stress.scm,
that model was used to remove entries from the lexicon which the model
correctly predicted thus allowing the lexicon to be much smaller.
