154 CHAPTER 5 ■ SPEECH

Example 5-12. notepad.gram
#JSGF V1.0;

/**
* JSGF Grammar for notepad example
*/

grammar notepad;

public <notepad> = (note pad);
public <exit> = (exit | good bye | quit);

Next, I need to create a class that will use this grammar file to actually launch a program.

Code Objective

The objective here is to perform basic speech recognition to open notepad, and then exit.

Code Discussion
After the grammar file, I need to create a configuration file for the recognizer. I used a provided
configuration file from one of the examples, but had to make a few modifications to the grammar
configuration for my class and my new grammar file. The configuration contains the other
following sections:
•word recognizer
• decoder

• linguist
•dictionary

• acoustic model
• unit manager
•frontend

• monitors
• miscellaneous

In the following configuration, the dictionary is defined later in the configuration file. This
contains all the words the recognizer can find.
