HMM Toolkit STK

Authors:

Lukáš Burget, Ondřej Glembek, Petr Schwarz, Martin Karafiát

Overview:

A set of tools for training and recognition of HMM's. Probably the most interesting in this distribution is 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.

Distributions:

The current version number is 2006_12_18

Binary distribution for Linux (I386), including some supporting scripts is available in stk_bin_linux-i386_2006_12_18.tgz

Source distribution is available in stk_src_2006_12_18.tgz

Examples:

Example of estimating HLDA transformation for HMM based phoneme recognizer.

Example of re-training phoneme recognizer using MMI and MPE criteria.

Example of re-training GMM based language recognition system using MMI criterion.
