| Abstract | This paper investigated the nonlinear nuisance attribute projection (NAP) in combined kernels for SVM-based speaker verification. The combined kernels approach enables the SVM classifier to use several different kinds of kernels together, e.g. linear kernel, RBF kernel, etc, for better classification. To compensate the session variability, which is one of the major reasons for performance degradation, nonlinear kernel NAP was used in this paper to projection out the attribute in the nuisance space which contains mainly the intra speaker variability. Experiments on NIST 2006 SRE corpora shows that, the combined kernels approach outperforms the conventional single kernel SVM approach, while the nonlinear NAP can further enhance this performance gains. |

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.
