If the AI revolution really is upon us then it's being led by a bunch of plastic cylinders doubling as Bluetooth speakers.

We can thank Amazon for kick-starting this trend with the release of the original Amazon Echo in 2014, but it's no longer the only game in town: Google released its own device, Google Home, last year and Apple will be following suit with the HomePod later this year.

So what's the point? And which should you buy? Read on for all the answers.
