Universal Grammar Modifications

The Nuance VWS1.3 browser comes with the universal grammars of 'help, cancel, exit' and 'repeat' turned on by default, meaning that these grammars are active unless specifically disabled. In both the Nuance VWS2.0 and Motorola browsers, these grammars are turned off by default, and as such, will not be available unless enabled by the developer. Note that if the grammar for it is not enabled, then the 'help' handler becomes a 'null' handler, which will never get hit from a user's utterance. To enable all of these grammars in your application, you will need to use the 'universals' property:



<property name="universals" value="all"/>

Or, you can activate specific grammars by inserting the values in a space-delimited list:



<property name="universals" value="help cancel exit"/>
