Package com.sun.speech.freetts.cart

Class Durator

java.lang.Object
com.sun.speech.freetts.cart.Durator
All Implemented Interfaces:
UtteranceProcessor
public class Durator extends Object implements UtteranceProcessor
Determines duration timing for Relation.SEGMENT relations in an utterance. Annotates the Relation.SEGMENT relation with an "end" time feature.

[[[TODO: The mean words-per-minute rate should become part of the CART data. For now, it is passed into the constructor.]]]

  • Constructor Details

    • Durator

      public Durator(CART cart, float meanRate, PhoneDurations durations)
      Creates a new duration UtteranceProcessor with the given CART and phone durations.
      Parameters:
      cart - contains zscore duration data
      meanRate - the mean words per minute rate of the CART data
      durations - contains mean and standard deviation phone durations

  • Method Details

    • processUtterance

      public void processUtterance(Utterance utterance) throws ProcessException
      Annotates the Relation.SEGMENT relations with cumulative "end" time features based on phone durations. Expects the CART to return a zscore for each phone, which specifies the number of standard deviations from the mean. This is coupled with a phone durations table that returns the mean and standard deviation for phones.
      Specified by:
      processUtterance in interface UtteranceProcessor
      Parameters:
      utterance - the utterance to process
      Throws:
      ProcessException - if a problem is encountered during the processing of the utterance
