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

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
