Class SimpleWordListGrammar

java.lang.Object
  extended byedu.cmu.sphinx.linguist.language.grammar.Grammar
      extended byedu.cmu.sphinx.linguist.language.grammar.SimpleWordListGrammar
All Implemented Interfaces:
Configurable

public class SimpleWordListGrammar
extends Grammar
implements Configurable

Defines a grammar based upon a list of words in a file. The format of the file is just one word per line. For example, for an isolated digits grammar the file will simply look like:

 zero
 one
 two
 three
 four
 five
 six
 seven
 eight
 nine
 
The path to the file is defined by the PROP_PATH property. If the PROP_LOOP property is true, the grammar created will be a looping grammar. Using the above digits grammar example, setting PROP_LOOP to true will make it a connected-digits grammar.

All probabilities are maintained in LogMath log base.

Method Detail

register

public void register(java.lang.String name,
                     Registry registry)
              throws PropertyException
Description copied from interface: Configurable
Register my properties. This method is called once early in the time of the component, shortly after the component is constructed. This component should register any configuration properties that it needs to register. If this configurable extends another configurable, super.register should also be called

Specified by:
register in interface Configurable
Overrides:
register in class Grammar
Throws:
PropertyException

newProperties

public void newProperties(PropertySheet ps)
                   throws PropertyException
Description copied from interface: Configurable
This method is called when this configurable component has new data. The component should first validate the data. If it is bad the component should return false. If the data is good, the component should record the the data internally and return true.

Specified by:
newProperties in interface Configurable
Overrides:
newProperties in class Grammar
Throws:
PropertyException
