La « grand-mère morte » d’Amazon Alexa n’est que le début du clonage vocal

 — 8 août 2022
The evolution of text to speech technology is bringing us closer to convincingly human-sounding voices

At the latest re:MARS conference, this june, Rohit Prasad, head scientist and vice president of Alexa AI, aimed to wow the audience with a paranormal parlor trick: speaking with the dead. “While AI can’t eliminate that pain of loss, it can definitely make their memories last,” he said, before showing a short video that starts with an adorable boy asking Alexa, “Can Grandma finish reading me The Wizard of Oz?”

The woman’s voice that reads a few sentences from the book sounds grandmother-y enough. But without knowing Grandma, it was impossible to evaluate the likeness. And the whole thing struck many observers as more than a little creepy—Ars Technica called the demo “morbid.” But Prasad’s revelation of how the “trick” was performed was truly gasp-worthy: Amazon scientists were able to summon Grandma’s voice based on just a one-minute audio sample. And they can easily do the same with pretty much any voice, a prospect that you may find exciting, terrifying, or a combination of both.
