ADAPTIVE DUAL COLLABORATIVE KALMAN FILTERING FOR VEHICULAR AUDIO ENHANCEMENT

摘要

A method includes: acquiring speech signals in a vehicle; dividing the speech signals into speech segments including one or more speech samples; processing a set of the speech segments using dual Kalman filters; and synthesizing the processed speech segments to construct noise-reduced speech signals. Each dual Kalman filter includes a first Kalman filter and a second Kalman filter, each speech segment in the set is processed using a different dual Kalman filter, and each speech segment in the set is processed in parallel with one another.
