Abstract
For improving the accuracy of a speech recognition system, for the specific task of character recognition, the character that is to be recognized or interpreted, is spoken in accordance with this invention, using simple coding-schemes that result in acoustic renderings that are well separated in the acoustic space. Furthermore, to relax the constraint on users for memorizing multiple words associated with multiple characters, in one embodiment, the coding-schemes are defined based on a combination of the given character and its neighboring/succeeding character(s).
