Class CompositeSenone

java.lang.Object
  edu.cmu.sphinx.linguist.acoustic.tiedstate.CompositeSenone

All Implemented Interfaces:

Senone, java.io.Serializable

public class CompositeSenone
extends java.lang.Object
implements Senone, java.io.Serializable

Represents a composite senone. A composite senone consists of a set of all possible senones for a given state. CompositeSenones are used when the exact context of a senone is not known. The CompositeSenone represents all the possible senones.

This class currently only needs to be public for testing purposes.

Note that all scores are maintained in LogMath log base

Returns:

a composite senone

dump

public void dump(java.lang.String msg)

Dumps this senone

Specified by:

dump in interface Senone

Parameters:

msg - annotatin for the dump

getScore

feature - the current feature

Returns:

the score for the feature in LogMath
