Class SentenceHMMStateArc

java.lang.Object

edu.cmu.sphinx.linguist.flat.SentenceHMMStateArc

All Implemented Interfaces:

SearchStateArc

public class SentenceHMMStateArc
extends java.lang.Object
implements SearchStateArc

Represents a transition in a sentence HMM. Each transition is described by the next state and the associated acoustic and language probability for the transition.

All probabilities are in the LogMath log domain
