If you have a system that simply activates Siri or Google like my car, then it works well, but if its anything like the integrated system in my other half's Focus, its a mess. You can't just say call ***
You have to say phone, dial name, then the persons name. If you get that far without it mishearing or simply cancelling then you deserve a pat on the back.
Pretty much how it works in my Mondeo. It's unusable. Siri is alright if it's something the phone can do, and tbh "hey Siri, call xxxx" works quite well.
