Abstract

pe1A dynamic keyboard includes a plurality of keys, each with an associated symbol, which are dynamically redefinable to provide access to higher level keyboards. 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 dynamically redefined keys can then provide the user with the ability to easily access both core and fringe vocabulary words in a speech synthesis system.
