3.3 Component Architecture
3.3.1 Implicit speech input component interface
The keyword spotting module is primarily designed to be used as a front-end to the topic
recognition Amigo context source.
Nevertheless, if you really want to use it as a stand-alone module, please use the following
procedure:
1. First, you need to instantiate a JAVA JulModule object, which represents your single
access point to the keyword recognizer. The JulModule object actually communicates
via socket with the real keyword recognizer, which is written in C. The JulModule object
further implements the JAVA swing Box interface that shows the keyword spotting
controls, which makes it easy for your application to add it to any of your graphical user
interface.
2. Then, you need to implement the JAVA RecoSubscriber interface, and to subscribe to
the JulModule object by calling the JulModule.subscribe(RecoSubscriber) method.
Whenever a new sentence has been recognized by the keyword spotting module, the
method RecoSubscriber.pushText(String) is called.
The interfaces are summarized next:
public interface fr.loria.parole.topicRecognition.RecoSubscriber
This interface shall be implemented by any object that exploits the output of the keyword
recognition module.
Method Summary
void pushText(java.lang.String s)
This method is called by the keyword recognition module whenever a new
sentence has been recognized from the speaker.
public class fr.loria.parole.topicRecognition.JulModule extends javax.swing.Box
This class is the main access point to the keyword recognition module It shall be instantiated by
the application that requires to access to the keyword recognition module. This class further
implements the javax.swing.Box interface, which makes it easy to include into any of the
application GUI. It then displays the GUI controls of the keyword recognition module.
Method Summary
void subscribe(RecoSubscriber sub)
This method MUST be called by the application that needs to be warned when
the user has uttered a new sentence.
