| Abstract | A novel Linear Prediction (LPC) based Automatic Speaker Identification (ASI) technique employing multiple representations of the LPC is presented. The proposed ASI system has two modes namely, the encoding mode, and the Speaker Identification (SI) mode. During the encoding mode, otherwise known as the training mode, the Linear Prediction Coefficients (LPC) are extracted for each speaker as speech features. Multiple Representation Split Vector Quantization (MRSVQ) is employed to form representative codebooks corresponding to each representation, for each speaker. During the SI (running) mode, the ASI system identifies the codebooks of the speaker in the database that best matches the LPC extracted from the speech signal of the unknown speaker. The synthesized all pole vocal tract transfer function is used as a measure of vocal tract for ASI. Employing the normalized vocal tract transfer function error measure, the proposed technique is consistently found to obtain enhanced ASI accuracy in comparison with vector quantization employing existing LPC representation, at the expense of a modest increase in computational complexity. Our ASI technique can be used in a stand-alone system or as part of an ASI environment. |

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.
