EURASIP Journal on Applied Signal Processing

  Special Issue on

  Advances in Multimicrophone Speech Processing

  Call for Papers

Speech quality may significantly deteriorate in the presence of
interference, especially when the speech signal is also subject
to reverberation. Consequently, modern communications systems,
such as cellular phones, employ some speech enhancement procedure
at the preprocessing stage, prior to further processing
(e.g., speech coding).

Generally, the performance of single-microphone techniques is
limited, since these techniques can utilize only spectral
information. Especially for the dereverberation problem, no adequate
single-microphone enhancement techniques are presently available.
Hence, in many applications such as hands-free mobile telephony,
voice-controlled systems, and teleconferencing and hearing instruments,
a growing tendency exists to move from single-microphone systems to
multimicrophone systems. Although multimicrophone systems come at an
increased cost, they exhibit the advantage of incorporating both
spatial and spectral information.

The use of multimicrophone systems raises many practical considerations
such as tracking the desired speech source and robustness to unknown microphone
positions. Furthermore, due to the increased computational load, real-time
algorithms are more difficult to obtain and hence the efficiency of the
algorithms becomes a major issue.

The main focus of this special issue is on emerging methods for speech
processing using multimicrophone arrays.

Topics of interest include (but are not limited to):

    o Source localization and tracking
    o Suppression of noise and interference
    o Speech enhancement
    o Acoustic echo cancelation and feedback suppression
    o Dereverberation
    o Blind speech source separation
    o Active noise control
    o Room acoustics modeling
    o Multimicrophone speech recognition
    o Applications to hands-free mobile telephony, voice-controlled systems,
      and teleconferencing and hearing instruments
