Initializes a new instance of the SrgsDocument class.
Namespace:
Microsoft.Speech.Recognition.SrgsGrammar
Assembly:
Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Sub New |
| Visual Basic (Usage) |
|---|
Dim instance As New SrgsDocument() |
| C# |
|---|
public SrgsDocument() |
Remarks
This constructor creates an empty SrgsDocument instance. To build a grammar within an empty SrgsDocument instance, add instances of classes that represent SRGS elements, such as SrgsRule, SrgsRuleRef, SrgsOneOf, and SrgsItem.
Examples
The following example creates an SrgsDocument object and then creates a public rule named rootRule. It then creates an SrgsItem that consists of the string "A nation that has won the world cup is:", and adds this item to the Elements property of the rule. The example then creates two more rules (ruleEurope and ruleSAmerica), each of which is an SrgsOneOf object that contains three SrgsItem objects. After that, another SrgsOneOf object is created that contains SrgsRuleRef objects that refer to ruleEurope and ruleSAmerica. The new SrgsOneOf object is then added to the Elements property of rootRule. After this, all three rules (rootRule, ruleEurope, and ruleSAmerica) are added to the Rules property of SrgsDocument. Finally, the three rules are compiled into a binary representation of the grammar.
