Hidden Markov Model Toolkit (HTK) from Cambridge University Engineering Department

HTK (Hidden Markov Model Toolkit)

Platform: Range of Unix platforms.
Description: HTK is a portable toolkit for building and manipulating hidden Markov models. HTK is primarily used for speech recognition research although it has been used for numerous other applications including research into speech synthesis, character recognition and DNA sequencing. HTK consists of a set of library modules and tools available in C source form. The tools provide sophisticated facilities for speech analysis, HMM training, testing and results analysis. The software supports HMMs using both continuous density mixture Gaussians and discrete distributions and can be used to build complex HMM systems. The HTK release contains extensive documentation and examples. HTK was originally developed at the Speech Vision and Robotics Group of the Cambridge University Engineering Department (CUED) where it has been used to build CUED's large vocabulary speech recognition systems
Misc 1: HTK is available free of charge and can be downloaded from a Web site http://htk.eng.cam.ac.uk
