Reduce the playlist volume while a certain voice is playing

Hello there,



I'm wondering how to lower the volume of the playlist when certain voices are playing and then return it to the original volume when the voices stop.



Here's the scenario:



While the heroine is working in the woods, there's an exciting background music (BGM) playing. When the heroine picks up a coin and says something cool, the BGM is too loud, making it difficult for the player to hear her. Ideally, when she says something, the BGM should temporarily decrease in volume until she finishes her line.



I've been using Master Audio for quite some time, but I've never utilized the pro features for tasks like this. Could you please provide some guidance?

Thanks!
