 Title of the Ph.D Thesis: - Automatic Identification of Indian languages based on various statistical approaches. 

Thesis Description:-Here work was mainly focussed  on  identification of Indian spoken languages especially prevalent in Northeast India.  Various existing statistical approaches were compared and a new hybrid approach was proposed for identification of Indian languages with our own recorded database. It has been proved from our experiments that our proposed hybrid approach is better than existing techniques. The research work was published in various IEEE conferences in India and abroad. Our work was also published in various unpaid international Journals like IJST, Springer (regular issue) and Inderscience. Details of the publications are given in Journals and conference listed below.
