This paper proposes an efficient noise reduction scheme for speech recognition in mobile devices. Due to the limited capacity of mobile devices, the speech recognition system requires a noise reduction module processed with low computational intensity. For noise reduction in mobile devices, the proposed approach directly utilizes packet data estimated by a speech coder. In particular, we apply pitch information for comb filtering, a well-known noise reduction method.
