1. A processing system for generating an output data set for use in phonemic synthesis to produce patterns of transition from one speech excitation state to another, said output data set including a plurality of output data subsets, said processing system comprising:

  • means for receiving a textual data set, said textual data set including at least one textual data subset;

    at least one memory storage device operable to store a plurality of processing system instructions; and

    at least one processing unit for generating said output data set by retrieving and executing at least one of said processing unit instructions from said memory storage device, said processing unit operable to;

    transform said received textual data set into a phonetic data set, said phonetic data set including a plurality of phonetic data subsets wherein each of said phonetic data subsets represents a particular speech state, said transformation modelling a number of acoustic parameters affecting the excitation sources of the vocal tract by deriving said parameters as nonlinear functions of a single excitation control variable; and

    interpolate said phonetic data set as a function of the single excitation control variable to generate said output data set whereby said phonetic data subsets are combined to determine their collective contributions to each one of said output data subsets.
