PolynomialF0Modeller

public PolynomialF0Modeller(java.lang.String locale,
                            java.lang.String propertyPrefix,
                            java.lang.String featprocClassInfo)
                     throws java.lang.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"
featprocClass - a package name for an instance of FeatureProcessorManager, e.g. "marytts.language.en.FeatureProcessorManager"
Throws:
java.lang.Exception

Method Detail

startup

public void startup()
             throws java.lang.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:
java.lang.Exception

process

public MaryData process(MaryData d)
                 throws java.lang.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
Returns:
A MaryData object of type outputType() encapsulating the processing result.

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

Throws:
java.lang.Exception

getMeanContour

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