Sporadic noise reduction for robust speech recognition in mobile devices
Jungpyo Hong, Jihoon Park, Seung Ho Han, Minsoo Hahn · 2011
In this paper, a framework of sporadic noise detection and cancellation is proposed. To improve the intelligence of sporadic noise detection, the difference residual detective signalbased detection algorithm is proposed. For performance evaluation, missing and false error rates, and speech recognition rates are measured. The results show remarkable performance improvement.
