1. An electronic speech-producing system for receiving allophonic code signals representative of allophonic units of speech and for producing audible speech-like sounds corresponding to the allophonic code signals, said speech-producing system comprising:

  • allophone library means in which digital signals representative of allophone-defining speech parameters identifying the respective allophone subset variants of each of the recognized phonemes in a given spoken language as modified by the speech environment in which the particular phoneme occurs are stored, said allophone library means being responsive to the allophonic code signals for providing digital signals representative of the particular allophone-defining speech parameters corresponding to said allophonic code signals;

    means operably associated with said allophone library means for concatenating the digital signals in a manner designating stress and intonation patterns;

    speech synthesizing means operably coupled to said concatenating means for receiving the digital signals representative of allophone-defining speech parameters and providing analog signals representative of synthesized speech corresponding to the digital signals received thereby; and

    audio output means operably connected to the output of said speech synthesizer means for receiving said analog signals representative of synthesized speech therefrom to produce audible synthesized speech-like sounds having stress and intonation incorporated therein.
