1. A 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, using a processor, based at least in part on a weighting of individual characters that comprise the known character sequence, wherein scoring the known character sequence comprises: determining whether a selected character of the known character sequence matches a selected character of the identified character sequence; when the selected character of the known character sequence matches the selected character of the identified character sequence: selecting a value that corresponds to the selected character of the known character sequence; and adding the selected value to a cumulative score associated with the known character sequence; and when the selected character of the known character sequence does not match the selected character of the identified character sequence: making no changes to the cumulative score associated with the known character sequence based upon the selected character of the known character sequence.
