Abstract
Most of the existing adaptive noise cancelling
techniques produce little improvement in the intelligibility
of speech for the hearing impaired in reverberant
environments. In this paper we propose
two-stage adaptive structures to improve speech intelligibility
in noise. The first stage removes the
interference and produces a distorted version of the
signal. The second stage then removes this distortion
and the clean signal is obtained. We suggest
two algorithms: an unconstrained and a constrained
one for the first stage. In high Signal-to-Noise Ratios
(SNR) both perform very well and more than 20dB
noise reduction may be achieved. In low SNR the
constrained algorithm performs better with a slight
increase in the computational load.
