ISOLATED TAMIL SPEECH RECOGNITION SYSTEM BASED ON CMU SPHINX

Speech is one of the most complex signals and the powerful tool for communication. Speech recognition has been a long desire of the scientists that the machine should recognize the speech of the human beings either for the machine to function on voice commands or for giving a text output of the speech. In this paper we present the creation of Tamil version of Automated Speech Recognition System (ASR).This system is based on the open source Sphinx-4, from the Carnegie Mellon University, which is a speech recognition system based on discrete Hidden Markov Models (HMMs). We investigate the changes that must be made to the model to adapt Tamil speech recognition.
