METHOD FOR GENERATING A TEXT-BASED INDEX FROM A VOICE ANNOTATION

摘要

The invention relates to a method for generating a text-based index (16) associated with images from a voice annotation (15). The inventive method consists in carrying out a speech recognition (25) applied to the voice annotation (15) with a predetermined recognisable vocabulary (17) in such a way that it makes it possible to search at least one word contained in the recognisable vocabulary (17) in the voice annotation, wherein said word or words identified during the search form the text-based index (16). Said method also comprises a step for defining the recognisable vocabulary consisting in defining (22) a context and in searching (24) a list of words associated with the context in a language system and in forming the recognisable vocabulary (17).
