| Abstract | The growing need to identify individuals becomes increasingly evident today, and biometrics are presented as the most safe and effective to perform this task. Among the various patterns that can be used in a biometric system, this work is dedicated to the study of the voice biometrics. Thus, a study of the area of voice processing and its applications were made and an architecture to systems of recognition and verification of a speaker was proposed. To that end, it was necessary to acquire a basic human voice to be built. The feature extractor MFCC (Mel Frequency cepstral coefficients) was used for the purpose of obtaining information that best representing each speaker. From the data obtained, was conducted a detailed study of the database (through statistical methods) and performance of Neural Networks MLP (Multilayer Perceptron) and SVM (Support Vectors Machines) were investigated to recognize the speakers. Besides In addition, the Vector Quantization also been applied to test speakers, showing satisfactory results. |

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.
