AutoVoice Autovoice - Best options?

Hi Guys, I'm building my new home with smarthome features, using Fibaro HC2, +Tasker, +Autovoice, and I am looking for the best settings for Autovoice Continuous.

My problem is, that although it is listening, sometimes it misses the commands. Sometime I am in the middle of the command -multiple words-, and it hears only the last few words, giving me -command not recognized-, or it ignores completely, because it stopped and started itself again.
So my questions are:
-if I start AV Cont., which options should I choose, for example, persistent notification?
-What is the proper Timeout setting?
-How can I eliminate the times between AV Cont. service stops, and restarts itself?
-It is okay to create an automatic task, which stopps, and restart AV Cont?
-How can I extend the distance between the talking person and the tablet? External Microphone? Whichone? Bluetooth mic. is not good, because AV is confirming commands on bluetooth ceiling speakers.
In general I would like to make it more reliable, and eliminate missed commands.

Thanks in advance,
Krisztia
