| Abstract | Traditional speech information hiding methods have several disadvantages, for example, constant embedding amplitude, lower speech quality, higher bit error rate. A novel speech information hiding method based on Itakura-Saito measure and psychoacoustic model is proposed. The embedding amplitude can be controlled by Itakura-Saito measure and psychoacoustic model together. The host speech is decomposed by wavelet packet transformation and then mapped into the critical bands. According to the audio masking threshold, the embedding amplitude in each subband can be determined. And then, the adjustment factors can be calculated by Itakura-Saito measure to control the embedding amplitude in each frame so that the speech quality is good. The embedding amplitude can be determined automatically. Experimental results show that the performance of this method is better than that of the traditional methods. |

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.
