iPhone 6s just talked to me saying "you have been selected to try iPhone X"

Hi All,

Today, my iPhone 6s, updated to the latest iOS just started talking to me while I was using the Whatsapp app. A robotic voice said "you have been selected to try iPhone X".

There was no banner or notification displaying, however I just noticed the buffer icon near the wifi connection. This is quite scary honestly. Does anyone know what it is and how to make sure my phone hasn't been hacked?

I am assuming it's a scam as I guess Apple would send me an email or a call if it was a true selection.

Thank you
