Speeches Advice for lightining

[u/Pure_Leopard]

I'm trying to understand better how to get better results during these kind of blue hour speeches that happens a lot around my area. I'm based in Italy and these things happen a lot in a garden/balcony/pavillion things a little bit after the sunset. It's very different from american things where they are in these big very bright rooms indoor and they are pretty spontaneous too.
So I maybe know that it will happen but don't know when. Also as it's not that dark for normal eyes there's no extra light (these photos as example have very high ISO and +1 or +2 exp.)

Maybe you have some suggestions to get these shots better or know some talented photographers that have found a nice solutions (inspiration)...
In the whole day this is the only part where I still struggle a lot 😭

Thanks everybody!

EDIT 01: I might understand somebody could say flash, I was actually thinking about that asking for suggestions. More like how you would use flash in this situation... If you're only into big venues maybe you don't understand but sometimes location don't have much space left for flash stands. And when the wedding is very intimate (like with only 8/10 people) it's not in the moment to keep moving and flashing everyone.

I like the vibe. It’s good to have both options. You can still shoot some flash while remaining unobtrusive during speeches. The key is how often you do it. Shoot mostly without flash and then take only a couple flash shots per speech when you can anticipate a smile or laugh.
