Definition

Namespace:

System.Speech.Recognition

Assembly:

System.Speech.dll

Package:

System.Speech v10.0.0-preview.1.25080.5

Source:

RecognizedPhrase.cs

Gets the semantic information that is associated with the recognized phrase.

C#

public System.Speech.Recognition.SemanticValue Semantics { get; }

Property Value

SemanticValue

The semantic information associated with the recognized phrase.

Examples

The following example defines a method that gets specific semantic information from a recognized phrase. When this method returns, it contains the value for the semantic key, or null if the value was not retrieved. This method checks only for top-level keys. Since the semantic information is contained in a tree of values, lower-level keys must be accessed through the returned semantic value.

static bool TryGetSemanticValue(  
      RecognizedPhrase phrase, string key, out SemanticValue value)  
{  
  value = null;  
  bool found = phrase.Semantics.ContainsKey(key);  
  if (found)  
  {  
    value = phrase.Semantics[key];  
  }  

  return found;  
}  

Remarks

A speech recognition grammar can include semantic information. When a speech recognizer generates a recognition result for such a grammar, the semantic information might be included in the recognition result, according to the rules of the grammar and the input to the recognizer. For more information about semantic information, see Understanding Semantic Results and the SemanticResultKey and SemanticResultValue classes.
