I'm with Danny - DAW automation rules.
Here's another idea: When I used to do a lot of this in the 1970s and 1980s I devised a clever patch to combine a 1/2 second delay and a compressor side-chain. The music went through the compressor, and its volume was controlled by the speaking voice using the side-chain. The voice was delayed half a second into the final mix, but not delayed into the side-chain. So when the announcer spoke the music would be turned down in anticipation
of the voice. I used a medium attack time and slow decay, to make the volume changes sound natural. If you have a long project, the time to set this up is more than offset by not having to program all those volume changes. And today, with total recall, once you have the setup you can use it again and again in the future.
