Amazon Alexa will be able to mimic deceased loved ones' voices

The latest iteration of Amazon's Alexa voice assistant could sound eerily familiar.

The company announced on Wednesday during its annual re:MARS conference, which focuses on artificial intelligence innovation, that it's working on an update to its Alexa system that would allow the technology to mimic any voice, even a deceased family member.

In a video shown on stage, Amazon (AMZN) demonstrated how, instead of Alexa's signature voice reading a story to a young boy, it was his grandmother's voice.
