title: Observation sequences format for HMM in speech recognition
body: <p>I am trying to develop a system to seperate garbage from non-garbage in speech recognition. I am using the jahmm implementation of the Hidden Markov Models. I'm confused about the format I should provide the training data to the system as the observation sequence. And what is each state in the HMM composed of? I tried reading the manual but couldnt understand. Thank you</p>
