Construction of an automaton compiling grapheme/phoneme transcription rules for a phoneticizer

摘要

A system checks the accuracy of a required graphic chain, e.g. usage errors. Modules constructs a phoneticizer by construction of an automaton compiling transcription rules and by determining probabilities of transitions between grapheme/phoneme correspondences. A dictionary of phonetic signatures is constructed by transcribing graphic chains from a graphic chains dictionary into phonetic signatures and linking the phonetic signatures to said graphic chains and determines probabilities of transcriptions of the graphic chains into the phonetic signatures. A transcription of the required graphic chain is determined into a request phonetic signature, and a probability of the preceding transcription is determined. In the phonetic signatures dictionary, phonetic signatures are looked up substantially identical to said required phonetic signature to derive therefrom attested graphic chains stored in the graphic chains dictionary.
