In this paper, a new approach based on model adaptation is proposed for acoustic mismatch problem. A specific bias model - residual noise model - is presented, which is the joint compensation model for additive and convolutive bias. The novel noise model is estimated on the basis of maximum likelihood manner. In conjunction with the Parallel Model combination (PMC), it is effective for noisy environments. The experiments have been done based on the Cambridge's HTK toolkit to implement the continuous Mandarin digit recognition in noisy environments.
