American fast food chain Taco Bell has announced an expansion of its artificial intelligence (AI) ordering system testing, with plans to roll out AI voice technology to hundreds of stores by the end of 2023. This initiative aims to reduce employee workload, improve order accuracy, shorten customer wait times, and ultimately drive profit growth. This move demonstrates the fast food industry's shift towards intelligent services. Yum! Brands has already tested AI technology at some Taco Bell drive-thrus in the U.S., with plans to introduce it at KFC locations in Australia in the future.
