The lexicon serves two purposes: first, it provides unit sequences for words; second, it provides optional classification of words (e.g., noun, verb, etc.). The meaning of a unit varies depending upon the recognition task. For example, for isolated word recognition, the unit could be a whole word. For large vocabulary continuous recognition, the unit could be a triphone.
