Interface: ISpeechRecognizer

Status Property

The Status property returns an object representing the status of the recognizer.

This method provides information for static features about the speech recognition (SR) engine such as the languages it supports. It also provides information for dynamic features such as current stream position the engine has recognized up to, and if the stream is actively being sent to the engine.

ISpeechRecognizerStatus

Set: (This property is read-only)
Get: An ISpeechRecognizerStatus that gets the property.

Example

This code sample demonstrates the Status method. After creating an instance for a recognizer, Status retrieves information about the recognizer. The class ID that created the engine, the supported languages, (in decimal format) and the current device position is displayed.

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

Paste this code into the Declarations section of the form.

The Form_Load procedure creates the recognizer.

Public WithEvents RC As SpSharedRecoContext
Public myGrammar As ISpeechRecoGrammar

Private Sub Form_Load()
    Set RC = New SpSharedRecoContext
    
    Set myGrammar = RC.CreateGrammar
    myGrammar.DictationSetState SGDSActive
    
    Dim recoStatus As ISpeechRecognizerStatus
    Set recoStatus = RC.Recognizer.Status
    
    'Display engine CLSID
    Label1.Caption = recoStatus.ClsidEngine & vbCrLf
    
    'Display supported languages
    Dim i As Long
    Dim x As Variant
    For i = 0 To UBound(recoStatus.SupportedLanguages)
        Label1.Caption = Label1.Caption & recoStatus.SupportedLanguages(i) & vbCrLf
    Next i
    
    'display audio position
    Label1.Caption = Label1.Caption & recoStatus.AudioStatus.CurrentDevicePosition
End Sub
