Interface: ISpeechRecoContext

CreateResultFromMemory Method

The CreateResultFromMemory method creates a recognition result object from a saved recognition result.

The result must have been created with ISpeechRecoResult.SaveToMemory.

SpeechRecoContext.CreateResultFromMemory(
     ResultBlock As Variant
) As ISpeechRecoResult

Parameters

ResultBlock

A Variant variable containing a saved recognition result.

Return Value

An ISpeechRecoResult object.

Example

The following Visual Basic form code demonstrates the use of the SpeechRecoContext.CreateResultFromMemory and ISpeechRecoResult.SaveToMemory. The application displays the text of the current recognition as well as the previous one. This application also plays the the retained audio associated with the last recognition.

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

A command button called Command1

Paste this code into the Declarations section of the form.

Public WithEvents RC As SpSharedRecoContext
Public myGrammar As ISpeechRecoGrammar
Dim gLastPhrase As Variant

Private Sub Form_Load()
    Set RC = New SpSharedRecoContext
    RC.RetainedAudio = SRAORetainAudio
    Set myGrammar = RC.CreateGrammar
    
    myGrammar.DictationSetState SGDSActive
    gLastPhrase = Empty
End Sub

Private Sub RC_Recognition(ByVal StreamNumber As Long, ByVal StreamPosition As Variant, ByVal RecognitionType As SpeechLib.SpeechRecognitionType, ByVal Result As SpeechLib.ISpeechRecoResult)
    If IsEmpty(gLastPhrase) = False Then
        Dim GetRecoResult As ISpeechRecoResult
        Set GetRecoResult = RC.CreateResultFromMemory(gLastPhrase)
        
        savedText = GetRecoResult.PhraseInfo.GetText()
        Label1.Caption = "Last phrase: " & savedText
        GetRecoResult.SpeakAudio
    End If
    
    Label1.Caption = Label1.Caption & vbCrLf & "New phrase: " & Result.PhraseInfo.GetText
    
    Dim thePhrase As Variant
    gLastPhrase = Result.SaveToMemory
End Sub
