I have read of all the different ways to get voice announcements working, but I am wondering, given specific constraints that I will out line, what is the most reliable.
I have the following devices capable in one form or another of making the announcement:
Celeron computer running Windows 7 SP1 (primarily used to run iSpy Connect for my IP Cameras)
i3 computer running Ubuntu 16.04 LTS (primarily used for Plex server and Minecraft server)
a couple of Tracfones running Android 4.4.2 (primarily used as paperweights and can’t run lannouncer because of android version)
The servers are in a centralized location and can be heard from master bedroom, living and dining rooms and kitchen. The phones can of course be placed anywhere. I need it to play announcements that can be heard in the above areas and I need reliability above all else.
