Abstract:     Methods and apparatus are provided for retrieving audio information based on the audio content as well as the identity of the speaker. The results of content and speaker-based audio information retrieval methods are combined to provide references to audio information (and indirectly to video). A query search system retrieves information responsive to a textual query containing a text string (one or more key words), and the identity of a given speaker. An indexing system transcribes and indexes the audio information to create time-stamped content index file(s) and speaker index file(s). An audio retrieval system uses the generated content and speaker indexes to perform query-document matching based on the audio content and the speaker identity. Documents satisfying the user-specified content and speaker constraints are identified by comparing the start and end times of the document segments in both the content and speaker domains. Documents satisfying the user-specified content and speaker constraints are assigned a combined score that can be used in accordance with the present invention to rank-order the identified documents returned to the user, with the best-matched segments at the top of the list.

What is claimed is:     1. A method for retrieving audio information from one or more audio sources, said method comprising the steps of:
  • receiving a user query specifying at least one content and one speaker constraint; and
  • comparing said user query with a content index and a speaker index of said audio source to identify audio information satisfying said user query.
