21. A computer program product comprising: a non-transitory computer readable storage medium having computer usable program code that, when executed, performs a method of processing speech, the method comprising: receiving a spoken utterance of a plurality of uttered characters; determining an identified character sequence by determining corresponding identified characters for individual ones of the plurality of uttered characters; selecting a plurality of known character sequences that potentially correspond to the identified character sequence; and for each selected known character sequence, scoring such known character sequence based at least in part on a weighting of individual characters that comprise the known character sequence, wherein scoring the known character sequence comprises: responsive to determining that a first character of the known character sequence matches a second identified character of the identified character sequence, selecting a value that corresponds to the first character of the known character sequence; and adding the selected value to a cumulative score associated with the known character sequence.
