 * @brief  Word dictionary for recognition
 *
 * This file defines data structure for word dictionary used in recognition.
 * It stores word's string, output string, phoneme sequence, transparency.
 * Beginning-of-sentence word and End-of-sentence word guessed from runtime
 * environment is also stored here.
 *
 * Please note that the N-gram vocabulary is stored in NGRAM_INFO and it
 * can differ from this word dictionary.  The reference from the word
 * dictionary to a N-gram vocabulary is done by wton[] member in WORD_INFO.
 * When used with DFA, the wton[] holds a category number to which each word
 * belongs.
