AutoVoice Let autovoice wait for Google now sound

Hey all together,
I have a problem.
Im using autovoice with Tasker to switch to different pages of my homescreen. Works very good.
But If i say "weather" for example i want that autovoice waits until the Google voice is finished and then begins with its event trigger.
I already tried to use "wait" in tasker but as soon as autovoice triggers the Event to autovoice the Google voice is being interrupted.

Does anybody know if its possible to wait here?

Sorry for my bad englisch.
Thanks for your help in advance.
