Speech recognition systems that operate in real world
environments have to be robust against additive noises. In this
work, a technique that uses a voicing-dependent exponent in the
computation of the filter-bank parameters to improve their
robustness to additive noise is presented. Speech recognition
experiments with the Aurora 1.0 database and recognition setup
are reported to show the potential of this new technique.
