[edit] 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. The difference is stress marks on vowels with levels 0, 1, 2; not all entries have stress however. For example, the following pronunciations are available for encyclopedia:
ENCYCLOPEDIA AH0 N S AY2 K L AH0 P IY1 D IY0 AH0 ENCYCLOPEDIA(2) AH0 N S AY2 K L OW0 P IY1 D IY0 AH0
