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? (lemmy.ml)

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.
