Apparatus for performing speech recognition to determine a particular alphabetic character, comprising:

• a) means for receiving acoustic spoken input comprising a single alphabetic character and a word association with the single character such that the first character of said word is intended to be the same as said single alphabetic character;
• b) a speech vocabulary recognition system for processing said acoustic input for recognizing said single alphabetic character and said word;
• c) means for attempting to match said single alphabetic character with the first character of said word;
• d) means, responsive to an unsuccessful attempt at matching said single character with the first character of said word, for storing information relating to the unsuccessful attempt into a history of unsuccessful attempts,
• wherein said stored history information is used to determine the alphabetic character for the spoken input.

A computer program product for performing speech recognition to determine a particular alphabetic character, said computer program comprising program code stored on a computer readable storage medium, which when executed on a computer, performs the steps of:

• a) receiving acoustic spoken input comprising a single alphabetic character and a word association with the single character such that the first character of said word is intended to be the same as said single alphabetic character;
• b) processing said acoustic input by using a speech vocabulary recognition system to recognize said single alphabetic character and said word;
• c) attempting to match said single alphabetic character with the first character of said word;
• d) responsive to an unsuccessful attempt at matching said single character with the first character of said word, storing information relating to the unsuccessful attempt into a history of unsuccessful attempts,
• wherein said stored history information is used to determine the alphabetic character for the spoken input.
