Title
Using a remotewireless microphone for speech enhancement in non-stationary noise
Abstract
As portable wireless audio-enabled devices become common, it is possible to form an ad-hoc network of such devices to enable high quality speech capture. In this paper, we consider the use of a remote wireless microphone placed close to a noise source, which transmits relevant information to the primary device, where it is used for noise reduction. Specific challenges introduced by such a scheme are addressed. It is seen that the proposed arrangement can result in a good amount of noise reduction in the presence of highly non stationary interferences such as music, where conventional single-microphone methods perform poorly. Improvements in segmental signal-noise-ratio of about 6-7 dB are observed when the method is applied to enhance noisy speech.
