Is this Google Calendar automation even possible?

I’m looking to check Google Calendar every minute to see whether an event is on and then have Alexa or Sonos read out: “The following event has started: {calendar entry title}”

Possible with code that’s out there now? I’ve integrated GCal and can see that an event is on but it only checks every 15 mins and I don’t know how to get the event title in to HA so that it could be read out by one of the TTS servies.

It looks like you cant change the update interval.
However for the tittle you can have a template like this:


This will read the tittle.

If you want to read the description change the “message” attribute to “descrpition”.
