According to femalefirst,  Amazon is developing the tech to allow the digital assistant to mimic any voice it hears from less than a minute of audio.

Rohit Prasad, Amazon's senior vice-president, explained that the company is aiming to "make the memories last" after "so many of us lost someone we love" during the pandemic.

Speaking at Amazon's Re:Mars conference in Las Vegas, he said: "We are unquestionably living in the golden era of artificial intelligence (AI), where our dreams and science fictions are becoming a reality."

The concept is controversial, with a documentary filmmaker using software to make the late chef Anthony Bourdain say words that he had never spoken.

Amazon are yet to give a timeline for when the feature could be launched.
