Special tone generated by the Apple HomePod helps the smart speaker pair with an iPhone

The Apple HomePod will pair with an iPhone through the use of an audible tone
Apple's HomePod will feature an automatic pairing technology that will be based on a tone created by the HomePod and detected by a nearby iPhone. Last month (Wake up! It is now September) an iOS 11 beta version discovered that Siri will read out a four-digit authentication and pairing code, which is entered into the user's iPhone. What might happen here is that the HomePod tone triggers Siri into releasing the authentication and pairing code. Once you receive the code, it is entered into a nearby iPhone. Pairing is complete, no fuss, no muss.
"Your iPhone is listening to a tone from the HomePod. Make sure it is nearby and unobstructed."-Pop up message from the Apple HomePod
Each smart speaker is essentially made up of a speaker (duh!) and a virtual personal assistant. Users can enable and disable smart home based appliances, stream music from certain apps, receive weather forecasts, sports scores, stock prices and access other information. Amazon's virtual assistant Alexa is now branching out and is available on the HTC U11, the Motorola Moto X4 and the Huawei Mate 9.
