HMM toolkit STK

This distribution includes SERest - a tool for embedded training of HMM's with supporting scripts. Key features of SERest include re-estimation of linear transformations (MLLT, LDA, HLDA) within the training process, and use of recognition networks for the training. More info here.

Phoneme recognizer based on long temporal context

The phoneme recognizer was developed at Brno University of Technology, Faculty of Information Technology and was successfully applied to tasks including language identification [4], indexing and search of audio records, and keyword spotting [5]. The main purpose of this distribution is research. Outputs from this phoneme recognizer can be used as a baseline for subsequent processing, as for example phonotactic language modeling.

Lattice Search Engine (LSE)

This package contains several tools. The main three of them are:
- indexing HTK lattices
- sorting the index
- searching in the sorted index for single words or phrases

Some of the features of these tools were not used for a long time and may contain bugs.
