Interface: ISpeechRecoContext

AudioInputInterferenceStatus Property

The AudioInputInterferenceStatus property returns information about interference with the audio input of the recognition context.

This information is usually returned by the ISpeechRecoContext Interference event.

Syntax

Set:	(This property is read-only)
Get:	SpeechInterference = SpeechRecoContext.AudioInputInterferenceStatus

Parts

SpeechRecoContext

The owning object.

SpeechInterference

Set: (This property is read-only)
Get: A SpeechInterference constant reflecting the interference type.

Example

The following code snippet demonstrates retrieving the interference status for the last recognition. It assumes a valid RecognitionContext and speech recognition code in place.

Public WithEvents RecognitionContext As SpSharedRecoContext

'Speech processing code here

Dim interference As SpeechInterference
interference = RecognitionContext.AudioInputInterferenceStatus

A more realistic example returns the Interference event. In this example, the event displays a message in the Label1 label item of the application's Form1.

Private Sub RC_Interference(ByVal StreamNumber As Long, ByVal StreamPosition As Variant, ByVal interference As SpeechLib.SpeechInterference)
    Form1.Label1.Caption = "Interference detected: " & interference
End Sub
