Class Utterance

java.lang.Object

edu.cmu.sphinx.alignment.tokenizer.Utterance

public class Utterance
extends java.lang.Object

Holds all the data for an utterance to be spoken. It is incrementally modified by various UtteranceProcessor implementations. An utterance contains a set of Features (essential a set of properties) and a set of Relations. A Relation is an ordered set of Item graphs. The utterance contains a set of features and implements FeatureSet so that applications can set/get features directly from the utterance. If a feature query is not found in the utterance feature set, the query is forwarded to the FeatureSet of the voice associated with the utterance.
