| Abstract | This paper proposes a new output-based method for assessing speech quality and evaluates its performance. The measure is based on comparing the output speech to an artificial reference signal representing the closest match from an appropriately formulated codebook. The codebook holds a number of optimally clustered speech parameter vectors, extracted from an undistorted clean speech database, and provides a reference for computing objective auditory distance measures for distorted speech. The median minimum distance is used as a measure of the objective auditory distance. The required clustering and matching processes are achieved by using an efficient data mining technique known as the self-organising map. Speech parameters derived from perceptual linear prediction (PLP) and bark spectrum analysis are used to provide speaker independent information as required by an output-based objective approach for speech quality measure. |

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.
