Speech activity detection (SAD) serves as a crucial front-end system to several downstream
Speech and Language Technology (SLT) tasks such as speaker diarization, speaker …

This article presents the preliminary research results on a novel method of amplitude
modulation demodulation that allows estimation of the modulating signal at a frequency …

The task of estimating the fundamental frequency of an audio signal, also known as pitch
tracking, has been a long-standing research area in speech signal processing. Recently …

Voltage fluctuations are common disturbances in power grids. Initially, it is necessary to
selectively identify individual sources of voltage fluctuations to take actions to minimize the …

In this paper, an efficient retrieval approach for encrypted speech based on biological
hashing and spectral subtraction is proposed. The proposed approach improves the impact …

In this article, a novel pitch determination algorithm based on harmonic differences method
(HDM) is proposed. Most of the algorithms today rely on autocorrelation, cepstrum, and lastly …

Condition monitoring is an important asset in the industry to improve the safety and
efficiency of the production chain. However, in heavy machinery–such as edge trimmers in …
