| Abstract | Quality of Experience (QoE) is a human-centric paradigm which produces the blue print of human behavioral states such as perception, emotion, cognition and expectation. Recent advances in neurophysiological monitoring tools have facilitated the study of frequency, time and location of neuronal activity to an unprecedented degree, as well as opened doors to a better understanding of human cognition, emotions and overall behavioral systems. These neurophysiological insights may provide more accurate and objective characterization of QoE metrics. This paper seeks to investigate neuronal activity generated by three different quality levels of a speech stimulus using electroencephalography (EEG). To this end, an electroencephalography (EEG) feature was computed based on the coupling between so-called delta and beta EEG frequency bands, which has previously been linked with negative behavioral characteristics (anxiety, frustration, dissatisfaction). The result indicates an increase in delta and beta coupling with a decrease in the speech quality levels. Additionally, neural correlates of a subjective affective scores (arousal and valence) were also computed and shown to be inversely proportional with EEG feature. These preliminary findings corroborate that emotions play a significant role in human quality and QoE perception. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
