Name Property

The Name property returns the name of the semantic property.

The Name is the name of the semantic property from the command and control grammar. This property must be explicitly marked with the PROPNAME label. This is often associated with an ISpeechPhraseProperty.ID which is a numeric identifier and is assigned by the PROPID label.

Syntax

Set:	(This property is read-only)
Get:	String = ISpeechPhraseProperty.Name

Parts

ISpeechPhraseProperty: The owning object.
String: Set: (This property is read-only)
Get: A String variable that gets the property.

Remarks

Either Name or Id (if available) may be used to identify the rule invoked. Some languages, such as Visual Basic, can use strings in a Case Select statement. Therefore, the rule Name may be used directly in the Case Select statement. Other languages, such as C/C++ can only use numeric values in switch statements. In this case, the Id is more appropriate.

Example

The following code demonstrates getting the Name and Id property from a command and control recognition.

To run this code, create a form with the following controls:

Two labels called Label1 and Label2

Paste this code into the Declarations section of the form.

The Form_Load procedure creates and activates a command and control grammar. The grammar file sol.xml is the solitaire grammar provided with the SDK. The path listed is for a standard SDK install and may be changed as needed.

If "play the red five" has been recognized, the application displays the recognized text in Label1. Label2 displays the additional information about the grammar properties. In this case, the rules would be "color" and "rank" along with their numeric values.
