Robust speech recognition technology for speech recorded and transmitted over narrow-band channels requires advances in several components of a speech recognition system: signal processing techniques that produce invariant feature sets; acoustic modeling and training that produce channel-independent acoustic models; noise cancellation techniques that mitigate the effects of impulsive and application-dependent transient noise.
