Class SimpleWordListGrammar

java.lang.Object
  edu.cmu.sphinx.linguist.language.grammar.Grammar
      edu.cmu.sphinx.linguist.language.grammar.SimpleWordListGrammar

All Implemented Interfaces:

GrammarInterface, 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.

Field Summary

static java.lang.String	PROP_LOG_MATH The property that defines the logMath component.
static java.lang.String	PROP_LOOP The property that if true, indicates that this is a looping grammar
static java.lang.String	PROP_PATH The property that defines the location of the word list grammar
