The special issue will be devoted to algorithms and systems that use speech recognition and other types of spoken audio processing techniques to retrieve information, and, in particular, to provide access to spoken audio content or multimedia content with a speech track.

Submission Deadline: 1 March 2011

The field of spoken content indexing and retrieval has a long history dating back to the development of the first broadcast news retrieval systems in the 1990s. More recently, however, work on searching speech has been moving towards spoken audio that is produced spontaneously and in conversational settings. In contrast to the planned speech that is typical for the broadcast news domain, spontaneous, conversational speech is characterized by high variability and the lack of inherent structure. Domains in which researchers face such challenges include: lectures, meetings, interviews, debates, conversational broadcast (e.g., talk-shows), podcasts, call center recordings, cultural heritage archives, social video on the Web, spoken natural language queries and the Spoken Web.
We invite the submission of papers that describe research in the following areas:

  • Integration of information retrieval algorithms with speech recognition and audio analysis techniques
  • Interfaces and techniques to improve user interaction with speech collections
  • Indexing diverse, large scale collections
  • Search effectiveness and efficiency, including exploitation of additional information sources

Last week I received word about the img(Anaktisi) image search engine from Savvas Chatzichristofis. This search engine is based on 2 new content based descriptors that combine color and edge features. The results look promising!

There is also an offline sketch based retrieval system being developed. A screencast can be found on YouTube.
