1. A method of synthesizing human audible speech from a multi-word string of text, the method comprising the steps of:

  • treating the multi-word string as a single prosodic paragraph by performing the steps of;

    assigning a pitch to the beginning of the multi-word string that is higher than at the end of the multi-word string; and

    assigning a pitch to a final end point of the string that is lower than the pitch at any point within the string;

    including, in the multi-word string, following at least one of the individual words in the multi-word string, the corresponding spelling of the individual word;

    treating each individual word in the multi-word string as a single word declarative sentence;

    treating the spelling of each individual word included in the multi-word string as a single word declarative sentence;

    grouping each individual word and the corresponding spelling of the individual word into a prosodic group within the single prosodic paragraph, the prosodic group having a higher pitch at the beginning of the prosodic group than at the end of said prosodic group; and

    generating speech from the multi-word string as a function of the prosodic groupings and assigned pitch.
