CA 2420093

A method for discriminating between an instance of a voice command and an instance of speech dictation can include identifying a focus point in a user interface; defining a surrounding region about the focus point; identifying user interface objets in the surrounding region; further identifying among the identified user interface objects those user interface objects which are configured to accept speech dictated text and those user interface objects which are not configured to accept speech dictated text; computing a probability based upon those user interface objects which have been further identified as being configured to accept speech dictated text and those user interface objets which have been further identified as not being configured to accept speech dictated text; receiving speech input; and, biasing a determination of whether the speech input is a voice command or speech dictation based upon the computed probability. Additionally, the method can include identifying a focus point outside of the user interface; and, biasing a determination of whether the speech input is a voice command or speech dictation based upon a default probability.

L'invention concerne un procédé de discrimination entre un exemple de commande vocale et un exemple de dictée orale, comprenant les opérations suivantes : identifier un point focal dans une interface utilisateur ; définir une zone environnante autour de ce point focal ; identifier les objets de l'interface utilisateur dans cette zone environnante ; parmi les objets de l'interface utilisateur identifiés, déterminer ceux qui sont configurés pour accepter des textes dictés oralement et ceux qui ne le sont pas ; calculer une probabilité basée sur les objets de l'interface utilisateur identifiés comme pouvant accepter des textes dictés oralement et sur ceux identifiés comme ne pouvant pas les accepter ; recevoir une entrée vocale ; solliciter une détermination, basée sur la probabilité calculée, pour savoir si l'entrée vocale est une commande vocale ou une dictée orale. En outre, ledit procédé peut comporter l'identification d'un point focal extérieur à l'interface utilisateur et la sollicitation d'une détermination, pour savoir si l'entrée vocale est une commande vocale ou une dictée orale, sur la base d'une probabilité par défaut.
