Accurate and effective voice activity detection (VAD) is a fundamental step for robust speech or speaker recognition. In this study, we proposed a hierarchical framework approach for VAD and speech enhancement. The modified Wiener filter (MWF) approach is utilized for noise reduction in the speech enhancement block. For the feature selection and voting block, several discriminating features wer...

This paper introduces the topic of " Collaborative Distance " within Distributed Collaboration as being an introduction to this Special Issue on Collaborative Working Environments 1 (CWE). It starts in discussing various related concepts, identified during an extensive literature review, on both proximity and distance in distributed collaboration. Then, a Collaborative Distance Framework (CDF) ...

We propose a new approach to commutative watermarkingencryption (CWE). A permutation cipher is used to encrypt the multimedia data, which leaves the global statistics of the multimedia data intact. Therefore, any non-localized watermarking scheme that depends only on global statistics of the multimedia data can be combined with the permutation cipher to form a CWE scheme. We demonstrate this ap...

If professional competencies were of any importance in any educational environment, they would be clearly and emphatically covered in teacher training and in-service training programs in that environment, leading to a common perception among both working teachers and student-teachers. To explore this situation here in Kordestan, a group of 16 student-teachers and 15 working teachers were interv...

Multiword Expressions (MWEs), a known nuisance for both linguistics and NLP, blur the lines between syntax and semantics. The semantic of a MWE cannot be expressed after combining the semantic of its constituents. In this study, we propose a novel approach called “semantic clustering” as an instrument for extracting the MWEs especially for resource constraint languages like Bengali. At the begi...
