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.

Syntax

Set:	(This property is read-only)
Get:	ISpeechRecognizerStatus = SpeechRecognizer.Status

Parts

SpeechRecognizer

The owning object.

ISpeechRecognizerStatus

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

Example

This code example demonstrates the Status property. After creating an instance for a recognizer, the code retrieves information about the recognizer's status: the class ID that created the engine, the supported languages, (in decimal format), and the current device position.

To run this code, create a form with no controls. Paste this code into the Declarations section of the form.

Option Explicit

Private Sub Form_Load()
    On Error GoTo EH

    Const NL = vbNewLine
    Dim i As Integer
    Dim myGrammar As ISpeechRecoGrammar
    Dim RC As SpSharedRecoContext
    Dim recoStatus As ISpeechRecognizerStatus
    Dim T As String

    Set RC = New SpSharedRecoContext
    Set myGrammar = RC.CreateGrammar
    myGrammar.DictationSetState SGDSActive

    Set recoStatus = RC.Recognizer.Status

    T = "Engine ID: " & recoStatus.ClsidEngine & NL

    ' Display supported languages--
    For i = 0 To UBound(recoStatus.SupportedLanguages)
        T = T & "Supported Language ID: "
        T = T & recoStatus.SupportedLanguages(i) & NL
    Next i

    ' Display audio position.
    T = T & "Audio Position: "
    T = T & recoStatus.AudioStatus.CurrentDevicePosition

    MsgBox T, vbInformation

EH:
    If Err.Number Then ShowErrMsg
End Sub

Private Sub ShowErrMsg()

    ' Declare identifiers:
    Dim T As String

    T = "Desc: " & Err.Description & vbNewLine
    T = T & "Err #: " & Err.Number
    MsgBox T, vbExclamation, "Run-Time Error"
    End
