In this paper, we present a speech enhancement method as a pre-processor in a car environment. For the friendly and safe use of the voice commander in a running car, non-stationary audio signals such as music and non-candidate speech should be reduced. Our technique is a two microphone-based one. It consists of two parts, i.e., blind source separation (BSS)(More)
This paper proposed the method that can efficiently detect the transient component existing in the multi-channel audio signal and accordingly extract spatial cues in order to improve the performance of the spatial cue based multi-channel audio coding. The proposed transient signal detection algorithm was implemented to use energy as well as the input signal(More)
