Finite-state machine is used as a core technology in many fields of natural language processing. The applications include speech recognition and generation, spelling correction, fact extraction, information retrieval and approaches to translation. This paper describes the design of finite state machine in development of a Malayalam spellchecker. Co...

This paper presents a chat application that make use of speech as interaction mode between users in their mother tongue. This system is based on Machine Translation (MT) which automatically translates a sentence from one language to other. Now-a-days, Chat has become increasingly important as an effective means to communicate in social networks. Bu...
