| Abstract | It has been observed that modern heavy industries are plagued with hazardous working environments like high temperature, high voltage etc. that pose a severe threat to the life of a human operator. Most common examples are steel plants and mines which report huge losses of life every year. Thus, there is a need to develop a system which any human personnel can use to control a process without exposing himself to any type of prevailing work hazards. This paper describes a remote voice control and security system (RVCS) to solve the above problem. It is a system that can control any process (e.g. switching ON/OFF a dc motor for experimental purposes) from anywhere in the world by vocalizing appropriate commands into a mobile phone. The hardware of the system comprises of a GSM handset connected to a TI TMS C6713 DSP Starter Kit via a stereo audio cable. An authorized operator at a remote location uses his GSM handset to connect to this system located at the process site. The system prompts the operator for access authentication (security feature) and once authenticated the user controls the plant operation by voicing the appropriate predefined commands (e.g. starting and stopping a motor). The DSK kit carries out real time speaker recognition for access authentication and speech verification for decoding the vocal commands. The software of the system has been developed in ANSIC in Code Composer Studio Platform. |

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.
