Namespace:
Microsoft.Speech.Recognition
Assembly:
Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Sub New ( _ phrase As String, _ minRepeat As Integer, _ maxRepeat As Integer _ ) |
| Visual Basic (Usage) |
|---|
Dim phrase As String Dim minRepeat As Integer Dim maxRepeat As Integer Dim instance As New GrammarBuilder(phrase, _ minRepeat, maxRepeat) |
| C# |
|---|
public GrammarBuilder( string phrase, int minRepeat, int maxRepeat ) |
Parameters
- phrase
- Type: System..::..String
The repeated sequence of words.
- minRepeat
- Type: System..::..Int32
The minimum number of times that input matching the phrase must occur to constitute a match.
- maxRepeat
- Type: System..::..Int32
The maximum number of times that input matching the phrase can occur to constitute a match.
Remarks
If the value of minRepeat is 0, then the new GrammarBuilder represents an optional element.
The value of minRepeat must be greater than or equal to 0 and less than or equal to the value of maxRepeat. For more information about building a speech recognition grammar that contains strings, see Use a String to Create a GrammarBuilder (Microsoft.Speech).
Examples
The following example creates a speech recognition grammar for ordering a pizza. It starts with an optional, opening phrase, followed by one to four toppings, and closes with the word "pizza".
| C# | Copy Code |
|---|---|
private static Grammar CreatePizzaGrammar()
{
// Create a Choices object with alternatives for toppings.
Choices toppings = new Choices(new string[] {
"cheese", "mushroom", "tomato", "onion",
"anchovy", "chicken", "pepperoni"});
// Create a GrammarBuilder and append the Choices object.
GrammarBuilder andToppings = new GrammarBuilder("and", 0, 1);
andToppings.Append(toppings);
// Construct the phrase.
GrammarBuilder gb = new GrammarBuilder("I would like a", 0, 1);
gb.Append(toppings);
gb.Append(new GrammarBuilder(andToppings, 0, 3));
gb.Append("pizza");
// Create the Grammar from the GrammarBuilder.
Grammar grammar = new Grammar(gb);
grammar.Name = "Pizza Order";
return grammar;
