Examples

The following example creates a grammar for choosing the cities for a flight. The example uses SrgsNameValueTag to assign a semantic value to each city, which is the code for the city's airport.

The example constructs two SrgsRuleRef instances, each of which specifies a semantic key. Both rule references target the same SrgsRule object, named cities, but tag the recognition result from the rule reference with a different semantic key. The semantic key identifies a recognized city as the departure city or the arrival city for the flight. The handler for the SpeechRecognized event uses the keys to retrieve the semantics values created using SrgsNameValueTag from the recognition result.
