Abstract :
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 signal-based detection algorithm is proposed. For performance evaluation, missing and false error rates, and speech recognition rates are measured. The results show remarkable performance improvement.
