== Abstract ==
The goal of speaker diarization is to determine when each participant speaks
in a recording. Such information is extensively used in ASR systems (for
example VTLN or in speaker adaptation) and for speaker indexing systems. It
is a part of the ongoing Rich Transcription (RT) evaluations organized by
NIST.

In recent years the increasing interest in speech/video analysis for the
meetings environment (NIST's RT05s and RT06s, AMI-DA-, CHIL and IM2
projects) made it necessary to address the possibility of having several
microphones recording synchronously. These can be either organized in
microphone clusters or spread across the room in unknown locations.

This presentation will cover the basics of what speaker diarization is and
the implementation proposed as part of the author’s PhD. The system
presented was built while at the International Computer Science Institute
(ICSI) for speaker diarization in the meeting environment and is has been
used for participation in the NIST RT evaluations since 2005. It is based on
a mono channel diarization system originally created for broadcast news
diarization, with a preprocessing step based on the delay&sum algorithm that
makes use of the multiple channels available for processing.

The later part of the talk will introduce the efforts recently started in
the speaker and audio indexing area in Telefónica R&D. Its impulse has
mainly come due to the Spanish I3media Cenit project which started this
year. Its objectives will be described, as well as the lines of research
taken up to this point.
