Amazon Echo smart speaker family expands
Amazon has revamped its main Echo smart speaker for the first time since its launch in 2014 and unveiled a range of associated devices.
The artificial intelligence-enhanced speaker helped establish a new product category and - although sales figures are not released - is thought to have outsold Google's rival Home by a wide margin.
The BBC's North America technology reporter Dave Lee went to the launch event in Seattle.
