SemanticValue.Value Property

Gets the information contained in the current SemanticValue.

Namespace: Microsoft.Speech.Recognition
Assembly: Microsoft.Speech (in microsoft.speech.dll)



Property Value

Returns a System.Object instance containing the information stored in the current SemanticValue instance.


Recognition results which do not make use of semantic parsing always have a Value of null and a Count property of zero.


The example below is used to recursively traverse and then display (as a Window.Forms.TreeNodeCollection) information, including confidence, or the nodes making up the tree structure of the semantics used to recognize a phrase. The use of Value is highlighted.

internal static void CreateSemanticsTreeNodes(TreeNodeCollection nodes,
                                              SemanticValue semantics,
                                              String name) {
    string semanticsText = String.Format("  {0} ( Confidence {1})",
       //Put integers as hex
    if (semantics.Value == null ){
        semanticsText = semanticsText + " = null";
    }else if (semantics.Value.GetType() == typeof(int)) {
        semanticsText = String.Format("{0} = {1:X} ", 
                                      semanticsText, semantics.Value);
    } else {
        semanticsText = semanticsText + " = "
                       + semantics.Value.ToString();
    TreeNode semanticsNode = new TreeNode(semanticsText);
    foreach (KeyValuePair<String, SemanticValue> child in semantics) {
        CreateSemanticsTreeNodes(semanticsNode.Nodes, child.Value, child.Key);
    //   }
