ABSTRACT:
The present invention relates to the field of computer-aided text and speech processing, and in particular to a method and respective system for converting an input text given in an incomplete language, for example a language, in which unvowelized text is used, into speech, wherein a computer-aided grapheme-phoneme conversion is used. In order to improve completion of the text, it is proposed toa) use statistical methods including decision trees and stochastic language models for enriching, i.e. completing said input text with missing information—which may be desired for a full understanding of the input textb) subjecting the completed input text to said grapheme-phoneme conversion to produce synthetic speech.Advantageously, the text is completed according to a model hierarchy giving higher priority to longer chunks of text, ie sentences (310, 315, 320) then multiword phrases (330, 335, 340), then words (350, 355, 360) and finally character groups (370, 375, 380, 390).
