| Abstract | Discriminative speaker features vary from one frame to another. Many researcher studied most of the discrimination features for speaker recognition by ignoring phonemic and linguistic information. However, other studies have proposed digital speech watermarking to improve the security of speaker recognition through channel transmission. Although digital speech watermark may be used with speaker information, it can affect speaker information which then can degrade the performance. This paper uses state-of-the-art in frame selection to propose a new way to preserve most of the discriminative features of speaker and to secure speech signals by applying digital speech watermarking technique. In this paper, linear predictive analysis was applied for each frame to extract formants, gain and residual errors. A frequency weighted function was used to quantify formants, and high order correlation as well as error gain is used for weighting the residual errors. The experimental results showed an overall (12 %) effectiveness in terms of performance, time and memory of frame selection technique for speaker recognition and digital speech watermarking. |

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.
