| Abstract | Parameters selection of support vector machine is a very important problem, which has great influence on the performance of support vector machine. Particle swarm optimization is an efficient algorithm and it is broadly used in many research areas like pattern recognition and so on. In order to improve the learning and generalization ability of support vector machine, a method for searching the optimal parameters based on particle swarm optimization is proposed in this paper. We constructed a speech recognition system based on support vector machine using the optimal parameters. The kernel function we used is radial basis function and the speech data is isolated, non-specific and middle vocabulary words. The speech feature we used is MFCC feature. Experiments indicate that the accuracy of speech recognition is efficiently improved by using support vector machine of the optimal parameters, which has practicability to some extent. This method provides an efficient approach for searching for optimal parameters of support vector machine. |

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.
