public class SpeakerDatabaseLoader
extends java.lang.Object

SpeakerDatabaseLoader is an auxiliary class that loads a speaker database from an external source, e.g. a text or XML file or a DBMS. The data read in is converted to objects of class speaker, and these objects are stored in a vector so that the original order is preserved.
