Mine too were 'silent watchers' for the first few months. Then around 6 months they really found their voice! And it's been yap, yap, yap ever since. One will set the other one off and they bark like crazy if anyone dares to drive down our road! And forget about someone ringing our doorbell, it's mayhem.
We are constantly working on the barking issue. It's a work in progress, but I'm optimistic!
