ECG is corrupted by various noises and denoising of ECG is central to proper diagnosis of cardiac diseases. The main objective of this work is to exploit the efficacy of non-local means (NLM) for ECG denoising. In the presented work, noisy ECG signal is decomposed into variational mode functions (VM…
A novel front-end speech parameterization technique that is robust towards ambient noise and pitch variations is proposed in this paper. In the proposed technique, the short-time magnitude spectrum obtained by discrete Fourier transform is first decomposed in several components using variational mod…
It is well known that, when noisy speech is transcribed using automatic speech recognition (ASR) systems trained on clean data, a highly degraded recognition performance is obtained. The problemgets further aggravatedwhen the targeted group happens to be child speakers. For children's speech, the ac…
