1. A computer program product for use with a computer system, comprising:

  • a computer usable medium having computer readable program code means embodied therein for causing a computer to transform a consistent message into a message recognizable by a computer, said computer program product havingfirst computer readable program code means for causing the computer to transform the consistent message generated by a human in at least two formats into electrical signal representations of the consistent message;

    second computer readable program code means for causing the computer to produce from said electrical signal representations of the consistent message a set of parameters for each said format;

    third computer readable program code means for causing the computer to generate a likelihood score of recognition from each said set of parameters;

    fourth computer readable program code means for causing the computer to use said sets of parameters to train a weighting coefficient for each of the at least two formats of the consistent message, wherein said training of a weighting coefficient further comprisespartitioning means for partitioning information in each said format into one or more subunits, wherein each subunit corresponds to a piece of the message,grouping means for grouping said subunits from each said format into a plurality of groups, wherein each said subunit in a group corresponds to the same piece of the message,first determining means for determining a likelihood score of recognition for each of said groups of subunits,second determining means for determining a global score for the information based on said likelihood score of recognition, andthird determining means for using said global score to determine said trained weighting coefficients;

    fifth computer readable program code means for causing the computer to generate a weighted expression based on said trained weighting coefficients and said likelihood scores of recognition; and

    sixth computer readable program code means for causing the computer to select a candidate message unit that maximizes said weighted expression to transform said electrical signal representations of the consistent message into a computer recognizable message.
