| SpeechRecognitionEngine..::..EmulateRecognizeAsync Method (array<RecognizedWordUnit>[]()[][], CompareOptions) |
| SpeechRecognitionEngine Class Example See Also Send Feedback |
Emulates input of specific words to the speech recognizer, using text in place of audio for asynchronous speech recognition, and specifies how the recognizer handles Unicode comparison between the words and the loaded speech recognition grammars.
Namespace:
Microsoft.Speech.Recognition
Assembly:
Microsoft.Speech (in Microsoft.Speech.dll)
Syntax
| Visual Basic (Declaration) |
|---|
Public Sub EmulateRecognizeAsync ( _ wordUnits As RecognizedWordUnit(), _ compareOptions As CompareOptions _ ) |
| Visual Basic (Usage) |
|---|
Dim instance As SpeechRecognitionEngine Dim wordUnits As RecognizedWordUnit() Dim compareOptions As CompareOptions instance.EmulateRecognizeAsync(wordUnits, _ compareOptions) |
| C# |
|---|
public void EmulateRecognizeAsync( RecognizedWordUnit[] wordUnits, CompareOptions compareOptions ) |
Parameters
- wordUnits
- Type: array<Microsoft.Speech.Recognition..::..RecognizedWordUnit>[]()[][]
An array of word units that contains the input for the recognition operation.
- compareOptions
- Type: System.Globalization..::..CompareOptions
A bitwise combination of the enumeration values that describe the type of comparison to use for the emulated recognition operation.
Remarks
The speech recognizer raises the SpeechDetected, SpeechHypothesized, SpeechRecognitionRejected, and SpeechRecognized events as if the recognition operation is not emulated. When the recognizer completes the asynchronous recognition operation, it raises the EmulateRecognizeCompleted event.
The only supported values of the compareOptions argument are OrdinalIgnoreCase and IgnoreCase. All other members of CompareOptions will generate a NotSupportedException exception or return a nullNothingnullptrunita null reference (Nothing in Visual Basic).
Emulated recognition ignores new lines and extra white space and treats punctuation literally, rather than letting it define phrases.
Examples
In the following example, an application obtains text input through a Textbox, and uses it to asynchronously emulate speech recognition.
Information about the emulated recognition is returned to the user interface by the anonymous method used as the handler for EmulateRecognizeCompleted events.
