How to use the HMM toolbox

Other packages for HMMs

• Matlab package for teaching HMMs for Mendelian genetics
• HTK3 from Cambridge University is open source C code for HMMs for speech recognition.
• Mathworks stats toolbox 4.1 contains some functions for discrete HMMs.
• Zoubin Ghahramani has matlab code which is very similar to mine (but doesn't handle mhmm's). He also has code for approximate (variational) inference in factorial HMMs.
• Matlab Speech processing toolbox
• More matlab speech processing routines
• GNU HMM toolbox implements the basic algorithms.
