HParse | The HParse program generates word level lattice files (for use with HVite), from a grammar file. |
HLEd | This program is a simple editor for manipulating label files. We use it to make word (or phone) level transcriptions of training data. |
HCopy | This program is used for generation of MFCC (Mel Frequency Cepstral Coefficients), which are required by HTK for model building, from recorded WAV files. |
HCompV | This Program calculates the global mean and covariance of a set of training data. We use this tool to create initial (HMM)values from the training data. |
HERest | This program is used to perform a single re-estimation of the parameters of a set of HMMs using an embedded training version of the Baum-Welch algorithm. |
HHEd | This tools is used in manipulating sets of HMM definitions. We used it to generate new states from combinations of existing ones. Especially silence models. |
HVite | HVite is a general-purpose Viterbi word recogniser. We use HVite to force-align testing data, and to calculate log-likelihoods when testing. |
HResults | HResults is the HTK performance analysis tool. It can be used for result statistics, such as word recognised percentages. |
