Hidden Markov Model (HMM) Toolbox for Matlab

This toolbox supports inference and learning for HMMs with discrete outputs (dhmm's), Gaussian outputs (ghmm's), or mixtures of Gaussians output (mhmm's). The Gaussians can be full, diagonal, or spherical (isotropic). It also supports discrete inputs, as in a POMDP. The inference routines support filtering, smoothing, and fixed-lag smoothing. For more general models, please see Bayes Net Toolbox.

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.
