Schema d'etiquettes, par mot NORMALISE (normalize() d'evaluate_asr.py) :
- casse : L (minuscule), C (Capitale initiale), U (TOUT EN MAJUSCULES, >= 2 lettres),
M (mixte, ex. "McDonald", "iPhone" : forme rendue via une table apprise)
- ponct. : signe qui suit le mot : O (aucun) , . ? ! : ;
("..." est compte comme "." ; guillemets, parentheses, tirets
d'incise ne sont pas predits : voir README).
Alignement texte brut -> mots normalises : normalize() agit caractere par
caractere a l'interieur de chaque jeton separe par des blancs (minuscules,
puis tout caractere hors [a-z0-9'-] devient un blanc, puis les jetons "-" et
"'" isoles sont supprimes). On rejoue exactement cette operation en gardant la
position de chaque caractere dans le texte brut : chaque mot normalise est
alors une plage du texte brut, d'ou on lit la casse ; le "trou" entre deux mots
(blancs, ponctuation, lettres accentuees supprimees) donne la ponctuation.
Si la reconstruction ne redonne pas normalize(texte).split(), l'exemple est
ignore et compte.
