CAPT and the verbo-tonal approach
“Or, ces mêmes critiques, formulées il y a plus de troisdécennies, s’adressent tout autant à l’EAO, dans la mesure où,sous le couvert d’un habillage informatif attractif, celui-civéhicule des pratiques et des contenus qui sont restés, audemeurant, fort traditionnels et peu innovants sur le planméthodologique”.

CAPT and the verbo-tonal approach
“Nous pensons aux aides informatiques visuelles pourl’enseignement de la prononciation telles que la visualisationde la configuration articulatoire à partir de diagrammesanimés, pour illustrer les mouvements des organesphonatoires ( qui se situe aux antipodes d’un travail derestructuration de la perception auditive), la visualisation descaractéristiques acoustiques des éléments segmentaux àl’aide de spectrogrammes ou d’oscillogrammes, lareprésentation visuelle des courbes mélodiques naturelles oustylisées, procédé intellectuel qui est à la correction de lamélodie ce que la méthode articulatoire est à la correctiondes sons et dont l’efficacité nous paraît pour le moinscontestable”.

CAPT and the verbo-tonal approach
“Les développements des outils informatiques peuvent ouvrirdes perspectives nouvelles à l’apprentissage de laprononciation, mais il serait regrettable de sacrifier laméthodologie des enseignants sur l’autel des technologiesnouvelles et de minimiser l’importance de la formation desmaîtres. Le risque est grand, en effet, que les enseignants nese retranchent derrière les NTICE pour s’exonérer d’unevéritable qualification professionnelle qui leur assure unetotale autonomie et les affranchisse de ce qui pourrait biendevenir une prothèse pédagogique”.
