Abstract
It comprises analyzing audio content of multimedia files and performing a speech to text transcription thereof automatically by means of an ASR process, and selecting acoustic and language models adapted for the ASR process at least before the latter processes the multimedia file, i.e. “a priori”.The method is particularly applicable to the automatic indexing, aggregation and clustering of news from different sources and from different types of files, including text, audio and audiovisual documents without any manual annotation.
