HTK - HMM Tool Kit A set of tools for training, testing and deploying Hidden Markov Models for statistical machine learning tasks, such as Speaker Verification and Recognition

The HTK (HMM Tool Kit) has been developed by the University of Cambridge. It contains a set of tools for training, testing (building) and eventual deployment of Hidden Markov Models (HMMs) primarily for speech recognition tasks. Its use, however, can be and has been extended to any machine learning/pattern recognition task.
