Hello who knows a site like => http://gw2timer.com
with the current meta of 2019 all with voice or sound notification
That site shows all events that have timers returned by Anet's services. Many metas are dynamic and require players to complete specific milestones and those are specific to each map instance. And for those, the event timer can't be predicted and won't be shown on the site.
For example, Battle of Dragonfall requires everyone on the map to upgrade each camp to tier 4 then do 1 or 2 other events before you fight Kralk. You can be almost ready to fight Kralk on your map, but then decide to join a group and get moved to another instance of Dragonfall and find out that they're so far ahead they've beaten Kralk and the other bosses and are seconds away from the reset.
If you want an in game notice they're are a number of items like this one:
Also GW2 Taco overlay program can show events
