public ParallelAcousticScorer()
Method Detail

register

public void register(java.lang.String name,
                     Registry registry)
              throws PropertyException
Description copied from interface: Configurable
Register my properties. This method is called once early in the time of the component, shortly after the component is constructed. This component should register any configuration properties that it needs to register. If this configurable extends another configurable, super.register should also be called

Specified by:
register in interface Configurable
Parameters:
name - the name of the component
registry - the registry for this component
Throws:
PropertyException

newProperties

public void newProperties(PropertySheet ps)
                   throws PropertyException
Description copied from interface: Configurable
This method is called when this configurable component has new data. The component should first validate the data. If it is bad the component should return false. If the data is good, the component should record the the data internally and return true.

Specified by:
newProperties in interface Configurable
Parameters:
ps - a property sheet holding the new data
Throws:
PropertyException - if there is a problem with the properties.

calculateScores

public Scoreable calculateScores(java.util.List scoreableList)
Scores the given set of Tokens. All Tokens in the given list are assumed to belong to the same acoustic model.

Specified by:
calculateScores in interface AcousticScorer
Parameters:
scoreableList - a list containing StateToken objects to be scored
Returns:
the best scoring scorable, or null if there are no more frames to score

getName

public java.lang.String getName()
Description copied from interface: Configurable
Retrieves the name for this configurable component

Specified by:
getName in interface Configurable
Returns:
the name

allocate

public void allocate()
              throws java.io.IOException
Allocates resources for this scorer

Specified by:
allocate in interface AcousticScorer
Throws:
java.io.IOException

deallocate

public void deallocate()
Deallocates resouces for this scorer

Specified by:
deallocate in interface AcousticScorer

startRecognition

public void startRecognition()
starts the scorer

Specified by:
startRecognition in interface AcousticScorer

stopRecognition

public void stopRecognition()
stops the scorer

Specified by:
stopRecognition in interface AcousticScorer
