Résumé

Cet article examine s'il existe des corrélats articulatoires correspondant aux divers degrés d'une opposition phonologique. On y démontre qu'en anglais, l'amplitude des mouvements impliqués dans l'articulation des voyelles tendues en syllabe ouverte (où elles sont généralement en opposition avec les voyelles relâchées) est supérieure à celle observée en syllabe fermée (où cette opposition est moins marquée). Une analyse de flux optique appliquée à des vidéos échographiques de mouvements de la langue a permis de déterminer l'amplitude de ces mouvements. L'avantage de ce type d'analyse est qu'elle permet une comparaison directe entre les locuteurs et l'obtention de mesures pendant toute la durée d'une production donnée.
