Taco Bell's parent company, Yum Brands, plans to introduce 'voice AI' technology in hundreds of locations by the end of the year to ease employee workloads, improve order accuracy, and reduce wait times, with the ultimate goal of increasing revenue. This technology has been in original testing for about two years in over 100 Taco Bell locations and has also been implemented in five KFC restaurants in Australia. Despite mixed results from AI experiments in the fast-food industry, Wendy's expressed satisfaction, while McDonald's has retracted related plans.
