The trascriptions must be exact and the tape cleanliness in order to individualize the voice, because the morphologic characteristics of system of phonation are only in the human being. The dialogue is studied anallyzed in different perspectives such as linguistically, semantically  and grammatically, what verbs it uses and how it uses them, if it omits phonemes. With judicial previous order, the cassettes are submitted to studies to determine how there is the original sound of each of the vowels and consonants since they go out of the vocal cords.
