A Lexicon in Festival is a subsystem that provides pronunciations for words. It can consist of three distinct parts: an addenda, typically short consisting of hand added words; a compiled lexicon, typically large (10,000s of words) which sits on disk somewhere; and a method for dealing with words not in either list.
