Microsoft Speech API 5.3

Recognizer Property

The Recognizer property identifies the recognizer associated with the recognition context.

Syntax

Set:	(This property is read-only)
Get:	ISpeechRecognizer = SpeechRecoContext.Recognizer

Parts

SpeechRecoContext
The owning object.
SpeechRecognizer
Set: (This property is read-only)
Get: A SpeechRecognizer object that gets the value of the property.

Remarks

Though it is usually acceptable to declare an object with the exact class name, ISpeechRecognizer is most often implemented as either SpSharedRecognizer or SpInprocRecognizer. Because it is not always known ahead of time which type of recognizer will be used, it is often safer to declare the object as Object.

Example

The following Visual Basic form code demonstrates retrieving the recognizer associated with recognition context, both for a Shared and an InProc recognizer. To run this code, paste it into the Declarations section of a form that contains no controls.

  
Option Explicit

Private Sub Form_Load()

    Dim RecoContext1 As SpInProcRecoContext
    Dim RecoContext2 As SpSharedRecoContext
    Dim Recognizer1 As SpInprocRecognizer
    Dim Recognizer2 As SpSharedRecognizer

    On Error GoTo EH

    Set RecoContext1 = New SpSharedRecoContext
    Set Recognizer1 = New SpSharedRecognizer
    Set Recognizer1 = RecoContext1.Recognizer
    MsgBox "Shared: " & Recognizer1.IsShared, vbInformation

    Set RecoContext2 = New SpInProcRecoContext
    Set Recognizer2 = New SpInprocRecognizer
    Set Recognizer2 = RecoContext2.Recognizer
    MsgBox "Shared: " & Recognizer2.IsShared, vbInformation

    End

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

End Sub
