Recent advances in computer technology and speech and
language processing have made possible that some new
ways of person-machine communication and computer
assistance to human activities start to appear feasible.
In this book, the use of a multi-microphone approach
to solve the problems introduced
by far-field microphones in speech applications
deployed in smart-rooms is investigated.
Microphone array processing is investigated as a
possible way to take advantage of the
multi-microphone availability for speech enhancement.
The use of microphone arrays for specific speech
recognition purposes in smart-room environments is
also discussed.
One limitation of microphone array processing is that
a reliable
speaker position estimation is needed to steer the
beamformer towards the position
of interest. Thus, robust speaker tracking is also
addressed and some novel proposals are presented.
Additionally, in the context of the development of
novel technologies that can provide additional
cues of information to the services deployed in
smart-room environments, novel acoustic
head orientation estimation based on multiple
microphones is investigated.
