All Implemented Interfaces:

public class WordAdaptiveSmoothingDeltifier
extends SmoothingDeltifier

TODO/possible extensions: - make incremental smoothing depend on currently salient actions (left is more likely after left, stop is more likely while moving)

Method Summary

private void	applyEditsToOutputLists(java.util.List<EditMessage<WordIU>> editsToBeApplied) apply edits to the output lists (wordIUs and wordEdits)
protected void	applySmoothingQueueToOutputWords() apply edits from smoothingQueue if their counter has run out, add them to edit list and update wordIUs in contrast to the overridden operation, this looks at *all* enqueued items (but stopping if it reaches a stay-safe-word), and if a counter has run out it enqueues also words preceding this word, for which the counter has not run out.
private java.util.List<EditMessage<WordIU>>	determineEditsToBeApplied(java.util.ListIterator<SmoothingDeltifier.SmoothingCounter> smoothIter) determine the edits from the smoothingQueue that should be applied if a counter has run out
protected int	getSmoothingFactor(EditMessage<WordIU> edit) more interesting assignment of smoothing factors depending on whether something is an "urgent word", a "stay-safe word", or just any other word
protected boolean	isStaySafeWord(EditMessage<WordIU> edit) determines the edits that should get a high safety-threshold words with action:drop should get a high smoothing factor,
protected boolean	isUrgentWord(EditMessage<WordIU> edit) determines the words that should be handled with priority words with action:stop should get a very low smoothing factor for the ADD message

Method Detail

newProperties

public void newProperties(edu.cmu.sphinx.util.props.PropertySheet ps)
                   throws edu.cmu.sphinx.util.props.PropertyException

Description copied from class: ASRWordDeltifier

this base implementation does not accept any parameters

Specified by:

newProperties in interface edu.cmu.sphinx.util.props.Configurable

Overrides:

newProperties in class SmoothingDeltifier

Throws:

edu.cmu.sphinx.util.props.PropertyException

getSmoothingFactor

protected int getSmoothingFactor(EditMessage<WordIU> edit)

more interesting assignment of smoothing factors depending on whether something is an "urgent word", a "stay-safe word", or just any other word

Overrides:

getSmoothingFactor in class SmoothingDeltifier

Parameters:

edit - ignored in this implementation

Returns:

smoothing factor for this edit; constant in this implementation

isStaySafeWord

protected boolean isStaySafeWord(EditMessage<WordIU> edit)

determines the edits that should get a high safety-threshold words with action:drop should get a high smoothing factor,

isUrgentWord

protected boolean isUrgentWord(EditMessage<WordIU> edit)

determines the words that should be handled with priority words with action:stop should get a very low smoothing factor for the ADD message

applySmoothingQueueToOutputWords

protected void applySmoothingQueueToOutputWords()

apply edits from smoothingQueue if their counter has run out, add them to edit list and update wordIUs

in contrast to the overridden operation, this looks at *all* enqueued items (but stopping if it reaches a stay-safe-word), and if a counter has run out it enqueues also words preceding this word, for which the counter has not run out. in other words: "jetzt stop" will be released as soon as "stop" goes off, even though "jetzt" may not have gone off yet.

Overrides:

applySmoothingQueueToOutputWords in class SmoothingDeltifier

determineEditsToBeApplied

private java.util.List<EditMessage<WordIU>> determineEditsToBeApplied(java.util.ListIterator<SmoothingDeltifier.SmoothingCounter> smoothIter)

determine the edits from the smoothingQueue that should be applied if a counter has run out

Parameters:

smoothIter -

Returns:

all the items in the smoothingQueue that *precede* the item for which the counter has run out (including that item)

applyEditsToOutputLists

private void applyEditsToOutputLists(java.util.List<EditMessage<WordIU>> editsToBeApplied)

apply edits to the output lists (wordIUs and wordEdits)

Parameters:

editsToBeApplied -

main

public static void main(java.lang.String[] args)

only for testing

toString

public java.lang.String toString()

Overrides:

toString in class SmoothingDeltifier
