Hidden Markov Model Toolkit
Hidden Markov Model Toolkit (HTK) is a portable software used to create and modify hidden Markov models. Although it has been utilized for a wide range of other purposes, such as research into speech synthesis, character recognition, and DNA sequencing, HTK is predominantly employed for speech recognition research.
HTK is made up of a number of tools and library modules that are available as C source code. The tools offer cutting-edge capabilities for HMM training, testing, and outcome analysis.
