Class Durator

  • All Implemented Interfaces:
    UtteranceProcessor

    public class Durator
    extends java.lang.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.]]]

      • 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

      • 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
