# This script normalizes the GlobalPhone Spanish dictionary. It removes the
# braces that separate word & pronunciation; removes the 'M_' marker from each
# phone; capitalizes the words; (optionally) tags the phones with language
# ('SW') marker; and (optionally) puts word-begin and -end markers or
# word-boundary markers on phones.
# *No special treatment for acronyms since some words are already capitalized.
