Method Detail

process

public MaryData process(MaryData d)
                 throws Exception

Description copied from class: InternalModule

Perform this module's processing on abstract "MaryData" input d. Subclasses need to make sure that the process() method is thread-safe, because in server-mode, it will be called from different threads at the same time. A sensible way to do this seems to be not to use any global or static variables, or to use them read-only.

Specified by:

process in interface MaryModule

Overrides:

process in class InternalModule

Parameters:

d - d

Returns:

A MaryData object of type outputType() encapsulating the processing result.

This method just returns its input. Subclasses should override this.

Throws:

Exception - Exception

listTargetFeatures

public String listTargetFeatures(TargetFeatureComputer featureComputer,
                        List<Element> segmentsAndBoundaries)

For the given elements and using the given feature computer, create a string representation of the target features.

Parameters:

featureComputer - featureComputer

segmentsAndBoundaries - segmentsAndBoundaries

Returns:

a multi-line string.

getListTargetFeatures

public List<Target> getListTargetFeatures(TargetFeatureComputer featureComputer,
                                 List<Element> segmentsAndBoundaries)

Return directly the targets, and set in each target its feature vector

Parameters:

featureComputer - featureComputer

segmentsAndBoundaries - segmentsAndBoundaries

Returns:

targets

overridableCreateTargetsWithPauses

protected List<Target> overridableCreateTargetsWithPauses(List<Element> segmentsAndBoundaries,
                                              String pauseSymbol)

Access the code from within the our own code so that a subclass can override it. Use this rather than the public static method in local code.

Parameters:

segmentsAndBoundaries - segmentsAndBoundaries

pauseSymbol - pauseSymbol

Returns:

TargetFeatureLister

createTargetsWithPauses

public static List<Target> createTargetsWithPauses(List<Element> segmentsAndBoundaries,
                                   String silenceSymbol)

Create the list of targets from the segments to be synthesized Prepend and append pauses if necessary

Parameters:

segmentsAndBoundaries - a list of MaryXML phone and boundary elements

silenceSymbol - silenceSymbol

Returns:

a list of Target objects
