How to know that SIRI is launched while my app is running?

Hi,

As the title, I figure out the throughput of iAP2(BT) is bad while launching siri. So that I want to reduce the data during using siri. Is any way to get that event? Search a lot I find a workaround solution https://stackoverflow.com/a/54822234/4562870. But in some case, it will be failed.

Is any idea for getting start & stop siri event? Please help or try to give some ideas how to achieve this. Thanks!
