Abstract
Speech in a motor vehicle is improved by suppressing transient, 'non-stationary' noise using pattern matching. Pre-stored sets of linear predictive coefficients are compared to LPC coefficients of a noise signal. The pre-stored LPC coefficient set that is 'closest' to an LPC coefficient set representing a signal comprising speech and noise is considered to be noise.
