Title (EN) ERROR CORRECTION FOR SPEECH RECOGNITION SYSTEMS
(FR) CORRECTION D'ERREURS POUR SYSTEMES DE RECONNAISSANCE VOCALE
Abstract:
(EN) Words in a sequence of words that is obtained from speech recognition of an input speech sequence are presented to a user, and at least one of the words in the sequence of words is replaced, in case it has been selected by a user for correction. Words with a low recognition confidence value are emphasized; alternative word candidates for the at least one selected word are ordered according to an ordering criterion; after replacing a word, an order of alternative word candidates for neighboring words in the sequence is updated; the replacement word is derived from a spoken representation of the at least one selected word by speech recognition with a limited vocabulary; and the word that replaces the at least one selected word is derived from a spoken and spelled representation of the at least one selected word.
(FR) Les mots d'une suite de mots provenant de la reconnaissance vocale d'une séquence vocale d'entrée sont proposés à un utilisateur, et l'un au moins des mots de la suite de mots est remplacé au cas où il a été choisi par un utilisateur pour corrections. L'accent est mis sur les mots à faible niveau de fiabilité de reconnaissance. D'autres mots candidats pour le mot choisi sont mis en liste selon un critère de classement. Après remplacement d'un mot, un ordre des mots de remplacement candidats pour les mots voisins dans la suite est mis à jour. Le mot de remplacement est dérivé d'une représentation parlée du mot sélectionné par la reconnaissance vocale avec un vocabulaire limité. Enfin, le mot remplacement le mot choisi est dérivé d'une représentation parlée et orthographiée du mot choisi.
