Abstract
A method of performing speech recognition to determine a particular alphabetic character can include receiving acoustic spoken input including a single alphabetic character and a word association with the single character such that the first character of the word is intended to be the same as the single alphabetic character. The acoustic input can be processed using a speech vocabulary recognition system to recognize the single alphabetic character and the word. An attempt to match the single alphabetic character with the first character of the word can be made and, responsive to an unsuccessful attempt at matching the single character with the first character of the word, information relating to the unsuccessful attempt can be stored into a history of unsuccessful attempts. The stored history information can be used to determine the alphabetic character for the spoken input.
