Which HMM libraries (hidden Markov models) have good support for Python?

I will need to train the HMM system (hidden Markov models). I was told that I can use the HTK or CSLU Toolkit . The first has a binding for Python, apparently called pyhtk .

Have any of you used this binding? Would you recommend me to go for it? Are there other HMM libraries with better Python support?

thank
