Abstract

La présente invention concerne des procédés et des systèmes de reconnaissance vocale (10) et d'apprentissage vocal (110). Selon l'invention, un utilisateur entre (28), par l'intermédiaire d'un microphone, des sons audibles dans un premier dispositif informatique comportant un programme avec une base de données (16). Cette base de données est constituée d'une représentation numérique de sons audibles connus et de représentations alphanumériques associées de ces sons audibles connus et de mauvaises prononciations. Le programme compare la représentation numérique d'un son avec les représentations numériques de sons audibles connus se trouvant dans une base de données (30) pour déterminer la probabilité d'avoir l'émission de sons désirés. Si une erreur se produit dans la reconnaissance (32), l'utilisation peut indiquer la représentation alphanumérique correcte du son audible (34) particulier. Cela permet au système de déterminer si l'erreur est le résultat d'un type connu ou d'un exemple de mauvaise prononciation (36). En réponse à la détermination de la nature de l'erreur, le système présente un programme d'apprentissage interactif offert par l'ordinateur à l'utilisateur pour permettre à ce dernier de corriger une telle mauvaise prononciation (45). L'avantage offert par la présente invention réside dans l'amélioration de la reconnaissance vocale et des modèles vocaux de l'utilisateur par forte implication de celui-ci dans la correction d'erreurs. Cela permet à l'utilisateur d'améliorer sa communication orale.
