1. A method of constructing a choice list of alternate versions of a recognized transcript from a speech recognition system, said method comprising:

  • during speech recognition, generating a list of close call records, wherein each record includes histories for each of two competing partial hypotheses;

    initializing the close call list from at least one output of the speech recognition system;

    selecting one of the close call records from the list of close call records;

    selecting a transcript from the choice list;

    determining whether one of the two histories for the selected record matches a partial subhistory of the transcript from the choice list;

    if one of the two histories for the selected close call record matches a partial subhistory of the transcript, substituting the other of the two histories for the partial subhistory of the transcript to generate an alternative version of the transcript; and

    , adding the alternative version of the transcript to the choice list.
