1. A speech recognition system that pre-processes speech data and inputs the pre-processed speech data in several forms to a voice recognition engine for determination of the most likely spoken word, comprising:

  • audio input means to input audio data comprised of phonemes;

    phoneme identification means to detect individual phonemes;

    wave segment grouping means to group phonemes into wave segments;

    a wave segment pre-processor to select groups of wave segments having at least one wave segment and output the selected wave segment groups to a speech recognition engine; and

    a speech recognition engine having means to compare wave segments groups output by the wave segment pre-processor with a predetermined list of words;

    means to determine which wave segment groups match entries in the predetermined list of words;

    whereby wave segments are pre-processed into wave segment groups and analyzed to determine which of the wave segment groups most likely represent words that are input to the speech recognition engine.
