This orange wire controls the buzzer for my intercom unit, reckon if I put a resistor between it and the screw it would lower the volume of the buzzer?

Only one way to find out.
Also, probably
- Hmm, guess I should probably figure out what size resistor I should use first
- Beat me to it
I‘d investigate whether the buzzer could be muzzled somehow. Sometimes a strategically placed piece of tape, or folded cloth, can do wonders.
Rather than a resistor, if you wire in a potentiometer you should be able to control the volume at the turn of a wheel or screw.
- That sounds cool but I only have resistors ATM, and regardless to change the volume I would need to hide it under the casing since this is a "stealth" modification that my apartment doesn't know about
  
  are you in the apartment right now?? Could they be watching you on the internet?
It depends if it's a voltage that's triggering the speaker via a circuit on that IC, or if it ends up powering the speaker directly, and I'd bet the former. Putting a resistor in series with one of the speaker leads is more likely to achieve what you're hoping for (without knowing more about the circuit).
Do voices and the buzzer sound come out of the same speaker shown in the picture, or is there a separate little "buzzer" speaker in there?
- This is your answer OP. Its likely a trigger voltage vs passing the current for the buzzer. Resistor likely won't achieve anything. But try it out.
Start by measuring the voltage and try one that reduces to half of it
- Oh God you know what I realized? That's gonna require me to be downstairs to ring our bell 🥲 gonna have to wait for my fiancée to come home to help me
  
  Just gotta order lots of food from different places!
  
  You can check the cables that comes from the button and short them, it should make the bell ring.
  
  Cant you use a phone or something to record the bell sound? I assume thats mainly what your fiancée would help you with.
I'd just slap a piece of cardboard or something like it over the buzzer hole itself
