| SemanticResultKey Constructor (String, array<String>[]()[][]) |
| SemanticResultKey Class Example See Also Send Feedback |
Assigns a semantic key to one or more String instances used to create a speech recognition grammar.
Namespace:
Microsoft.Speech.Recognition
Assembly:
Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Sub New ( _ semanticResultKey As String, _ ParamArray phrases As String() _ ) |
| Visual Basic (Usage) |
|---|
Dim semanticResultKey As String Dim phrases As String() Dim instance As New SemanticResultKey(semanticResultKey, _ phrases) |
| C# |
|---|
public SemanticResultKey( string semanticResultKey, params string[] phrases ) |
Parameters
- semanticResultKey
- Type: System..::..String
The tag to be used to access the SemanticValue instance associated with the Stringobjects specified by the phrases argument.
- phrases
- Type: array<System..::..String>[]()[][]
One or more String objects whose concatenated text will be associated with a SemanticValue object accessible with the tag defined in semanticResultKey.
Remarks
When performing a recognition operation, the String instances referred to in the phrases argument are treated as sequential. For example, if the following SemanticResultValue is used to construct a Grammar, input to the recognition engine must contain "the quick brown fox" to be recognized.
| C# | Copy Code |
|---|---|
SemanticResultKey stringTest=new SemanticResultKey("stringTest",
new string[] {
"the",
"quick",
"brown",
"fox"}); | |
The semanticResultKey argument determines the key used to access the SemanticValue.
If you construct a Grammar using a GrammarBuilder object that contains a semantic key with an array of string objects, the Value of the SemanticValue produced by a recognition operation will be the string used in recognition. In the preceding example, this means that Value would be "the quick brown fox".
Examples
The following example creates a Grammar from a GrammarBuilder object that uses a SemanticResultKey, which is defined by an array of String objects.
A recognition engine using the Grammar created will recognize the phrase "color red green blue zero". The semantics of the RecognizedPhrase returned by recognition will contain a SemanticValue with a Value of "red green blue". You can access the SemanticValue using the "code" tag.
Because of the SemanticResultValue("zero", 5) appended to the GrammarBuilder, the root SemanticValue object in the RecognizedPhrase will have a value of 5.
| C# | Copy Code |
|---|---|
private void keyTest()
{
//Say "color red green blue zero"
GrammarBuilder gb = new GrammarBuilder("color") +
new SemanticResultKey("code",
(new string[] {"red", "green", "blue"})) +
new SemanticResultValue("zero", 5);
Grammar g = new Grammar(gb);
g.Name = "keyTest";
_recognizer.LoadGrammar(g);
