1. A method of semantic, syntactic and/or lexical correction of an erroneous expression in a digital text, comprising: using a computer, transforming a digital text comprising eventual erroneous textual expressions into a digital voice message, in which at least one grapheme of the digital text comprising eventual erroneous textual expressions is converted into at least one phoneme comprising an intelligible vocal expression of the entire digital text, including any erroneous textual expressions, using the computer and pre-established writing rules, processing the digital voice message obtained at the transformation step, in which the at least one phoneme comprising the intelligible vocal expression is converted into at least one grapheme comprising a new digital text in which any erroneous textual expression is corrected, during the transformation step, providing the at least one phoneme according to a predetermined voice model, with the aid of a voice model base, and during, the processing step, identifying the at least one phoneme to be converted, with the aid of a base of recognition rules for the predetermined voice model.
2. The method as claimed in claim 1 , further comprising: before the transformation step, using the computer, providing a digital set of textual information data representative of the digital text with the erroneous expression, wherein the transformation step comprises converting the set of textual information data into a digital set of vocal information data representative of the at least one phoneme associated with the at least one grapheme of the digital text, including the at least one phoneme comprising the intelligible vocal expression, and wherein the processing step comprises converting the vocal information data provided by the conversion operation of the transformation step, into a digital set of textual information data representative of a reconstituted digital text including the corrected textual expression.
