The ability of resumable subs to return values (added in B4A v7.3) makes it very simple to add voice recognition to your app.

Code:
B4X:
Private Sub RecognizeVoice As ResumableSub
   vr.Listen
   Wait For vr_Result (Success As Boolean, Texts As List)
   If Success And Texts.Size > 0 Then
     Return Texts.Get(0)
   End If
   Return ""
End Sub
You can call it like this:
B4X:
Wait For (RecognizeVoice) Complete (Result As String)
Example:
B4X:
Sub Activity_Click
   Wait For (RecognizeVoice) Complete (Result As String)
   If Result <> "" Then
     Activity.Title = Result
   End If
End Sub
Example is attached.

When it fails to recognize the voice, it prompts the user to try again by clicking on the button in the dialog.

How to abort it?
