Constructor Detail

PolynomialF0Modeller

public PolynomialF0Modeller(String locale,
                    String propertyPrefix,
                    String featprocClassInfo)
                     throws Exception

Constructor which can be directly called from init info in the config file. Different languages can call this code with different settings.

Parameters:

locale - a locale string, e.g. "en"

propertyPrefix - the prefix to be used when looking up entries in the config files, e.g. "english.f0"

featprocClassInfo - a package name for an instance of FeatureProcessorManager, e.g. "marytts.language.en.FeatureProcessorManager"

Throws:

Exception - Exception

PolynomialF0Modeller

protected PolynomialF0Modeller(Locale locale,
                    String propertyPrefix,
                    FeatureProcessorManager featureProcessorManager)

Constructor to be called with instantiated objects.

Parameters:

locale - locale

propertyPrefix - the prefix to be used when looking up entries in the config files, e.g. "english.f0"

featureProcessorManager - the manager to use when looking up feature processors.

Method Detail

startup

public void startup()
             throws Exception

Description copied from interface: MaryModule

Allow the module to start up, performing whatever is necessary to become operational. After successful completion, getState() should return MODULE_RUNNING.

Specified by:

startup in interface MaryModule

Overrides:

startup in class InternalModule

Throws:

Exception - Exception

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

getMeanContour

protected double[] getMeanContour(FeatureFileReader currentContours,
                      int[] contourIDs)
