HMM Toolkit STK


Lukáš Burget, Ondřej Glembek, Petr Schwarz, Martin Karafiát


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.


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
