Based on sequenced symbols of keys sequentially activated, certain dynamic categories and subcategories can be accessed and keys corresponding thereto dynamically redefined. Dynamically redefined keys can include embellished symbols and/or newly displayed symbols. These dyanmically redefined keys can then provide the user with the ability to easily access both core and fringe vocabulary words in a speech synthesis system.Other References
