Bluetooth Speaker microphones: Can they be used for "Hey Siri"? I'm considering purchasing a Bluetooth portable speaker that has a built-in omnidirectional microphone.

The advertising for the product says that the microphone can be used to "make calls" from a mobile device.

However, I can't find out from the support pages if the microphone is "always on", or if it's just used for Call Audio Routing – as in iOS's Settings &gt; General &gt; Accessibility &gt; Call Audio Routing.

My aim, ultimately, is to use the Bluetooth speaker for playing audio from my iOS device, but also to use it as an always-on microphone that can accept "Hey Siri" voice detection commands.

Basically – an "Amazon Echo" device, but consisting of an iPad + Bluetooth speaker instead.

Is "Hey Siri" detection normally possible with mic-equipped Bluetooth speakers?



Specific case: I'm looking at a Bang &amp; Olufsen Beoplay A1.
To corroborate, my BT speaker-with-mic (a FuGoo) and BT-capable car (a 2012 Mazda) will will route microphone input and speaker output to Siri, but only if she's summoned by button press (long press of the play/pause button on the speaker, long-press of the iPhone's home button in the car). Neither will work with "Hey Siri". I suspect that one obstacle is that neither device has its microphone continuously listening - they are only activated when needed (a call comes in or you trigger Siri manually).

I suspect if a BT speaker manufacturer could make "Hey Siri" work, they'd be sure to list it in their list of advertising bullet points.
