I believe the best way to interact with Siri is through the Apple Watch, something that is always attached to you and doesn't require you to shout across the room. The Watch also connects to Wifi, and can work independently of the iPhone, allowing Siri, iMessage, calling etc. Also, the siri speaker has to deal with the possibility of multiple users using "Hey Siri" while the apple watch can be tied to an individual person.
