15. The system of claim 13 wherein said concatenating means further includes means for designating a pitch parameter for the allohpone-defining speech parameters as represented by the digital signals from said allophone library means corresponding to said allophonic code signal output.
15. The system of claim 13 wherein said concatenating means further includes means for designating a pitch parameter for the allohpone-defining speech parameters as represented by the digital signals from said allophone library means corresponding to said allophonic code signal output. 16. The system of claim 15, wherein the digital characters representative of printed data as recieved by the input of said allophone rules processor means are modified to include stress code data therein identifying portions of the digital character input corresponding to syllables in the printed data which are to be stressed, the allophonic code signal output from said allophone rules processor means reflecting the stress code data in the digital characters received thereby such that the digital signals provided by said allophone library means in response to said allophonic code output are representative of allophone-defining speech parameters including the syllable stress as identified by the stress code data, and said pitch parameter-designating means being responsive to said digital signals provided by said allophone library means for designating a base pitch parameter for the allophone-defining speech parameters as modified by the syllable stress included therein.
