Still, these terms if in such a way intercross and find treatment of a side as of another one, either in function of its vast fan of metodolgicas possibilities, either in function of the constituent dialectic of the proposal of characterization of the speech of Fairclough.O discursivo event present practical discursivas and motivated no-discursivas structurally, but on the other hand, the citizens are that they are all the moment ressignificando, placing the structures at risk in its practical discursivas. The structures and the practical ones show with a fluidity without precedents, that recoloca the citizen, actor now motivated is intentional or ideologically, again in the center. What it is basic in the Analysis of the Speech is sophistication in the definition of the structure of the language, or the lingustica materiality? expression that in supplies a more complete idea to them about what is the language: a cloudy structure, crossed for the events partner-descriptions. Exactly thus, for Fairclough the discursiva analysis of the French school is treated in very narrow semantic terms. The critical one if explains in part for the exhausting work on the discursiva surface, supported in questions of literal cohesion and coherence. Now, it invalidates completely inside of the perspective of the Analysis of the Speech: what it interests is not in the surface of the speech, it only contains the elements that supply to the analyst the access to the discursivo object. What it is in game is the explicitao of the mechanisms of production of directions. The Analysis of the Speech, in turn, can be divided in three phases, whose transformation Michel Pcheux flame of philosophical conversion of the look. The first phase is characterized by the effort of teorizao of an automatic structural-discursiva machine. This proposal of analysis of the speech is inaugurated in 1969 with the launching of the book Automatic Analysis of the Speech of Pcheux, whose proposal it is presentation of algorithms for the automatic analysis of speeches, supported in the method of Harris (Discourse Analysis – 1952).
