Word-by-word, grapheme-by-grapheme phoneticization is not particularly difficult to achieve in French. This is why ourmini-dico (minimal version) has only 337 rules. However, if one is to transcribe adequately a continuous text which hasn't been determined in advance, it is indispensable to proceed as we have done, by bringing into action the notions offrequency (the central pillar of the system),syntax, morphology, lexical or graphemiccontexts, and naturally also alexicon of exceptions, kept to a minimum. Experience has shown us that a person listening to an artificial voice is very demanding where the details are concerned: he cannot bear to listen to monotonous intonation, and is exasperated by syntax errors. Moreover, the progress which remains to be made in the field of dialogue between man and the machine cannot allow for this aspect to be perfected to a lesser degree than the others. Finally, and this is the point which comes closest to our own preoccupations, the written language has its own code of laws, linguistic laws operating in several levels, and which deserve to be treated as such, on a par with the others.
