1. A computer based method for direct recognition of coded speech data, the coded speech data generated by a compression algorithm, the compression algorithm generating from a digitized representation of a speech signal a data representation of a set of one or more speech component vectors, the computer-based method comprising the steps of:

  • a. transforming the data representation of the set of one or more speech component vectors into a corresponding data representation according to a base feature type, the transforming performed using a mapping algorithm, the mapping algorithm developed by comparing the data representation of the set of one or more speech component vectors defining a waveform with the corresponding data representation according to the base feature type defining the same waveform;

    b. obtaining one or more features from the corresponding data presentation according to the base feature type; and

    c. generating a recognition result in accordance with the one or more features obtained.
