Amazon debuted a more sophisticated version of Alexa on Wednesday that’s more conversational and can handle tasks on your behalf. But in a surprising departure from its usual playbook, the company didn’t announce new Echo devices to go with its revamped digital helper.

Amazon on Wednesday unveiled the first major overhaul of its Alexa voice assistant since its introduction more than a decade ago, embedding it with generative artificial intelligence.

Amazon is aiming to catch up in generative artificial intelligence and to reboot its virtual assistant, which has been leapfrogged by powerful chatbots.
