AutoVoice Voice input box: how to close automatically if nothing recognized

Hello, everybody.
Help with the problem, please.
I have a tasker task where there's an action Autovoice recognize. After this action the task must stop if nothing recognized or what is recognized doesn't match to certain words. It's ok in second case, but if nothing recognized a voice input box continues hang on suggesting to press to repeat. Is there any opportunity for that dialog box to close itself if nothing recognized. The best way for me in this task is to hide the dialog box, but recognition doesn't work properly in this case (sometimes a start signal doesn't sound etc).
