Yes. Taco Bell uses voice AI to take drive-thru orders at more than 890 U.S. locations across 38 states, according to a July 7, 2026 report by Restaurant Dive. That is a large but partial rollout—not evidence that every Taco Bell has AI ordering. The chain has continued expanding after reported complaints and abuse led Yum Brands to slow and reconsider deployment in 2025.
How Taco Bell’s AI drive-thru rollout changed
| Date | What was announced or reported | How to read the figure |
|---|---|---|
| July 31, 2024 | Yum! Brands said voice AI was already operating at more than 100 Taco Bell U.S. drive-thrus in 13 states, with a goal of reaching hundreds by the end of 2024. | The year-end number was a target, not a later verified count. Yum’s announcement did not establish whether it was met. |
| March 18, 2025 | Yum announced an NVIDIA collaboration, with AI pilots at select Taco Bell and Pizza Hut locations and a broader 500-restaurant rollout across Taco Bell, Pizza Hut, KFC and Habit Burger planned for Q2 2025. | The 500-location figure covered four brands and was a plan in the announcement, not proof of completion. Yum’s NVIDIA announcement does not establish how that plan was carried out. |
| August 2025 | Restaurant Dive later reported Yum slowed and reconsidered deployment after customer complaints and people abusing the ordering system. | This describes a rethink during adoption, not a complete abandonment or a measured system error rate. Taco Bell later said it remained committed to voice-AI expansion. |
| April–July 2026 | Omilia’s April case study reported deployment at more than 890 Taco Bell U.S. stores; Restaurant Dive reported more than 890 units in 38 states in July. | The later count is attributed to the vendor and a trade publication, rather than an independently audited rollout total. The reports describe Omilia’s partnership; they do not establish that it is the same system as the NVIDIA-related work. |
What the voice AI does—and what is not established
The system takes spoken drive-thru orders. Omilia’s April 2026 case study describes speech recognition, language understanding, filtering background noise, adapting to menu and stock changes, and handling accents, slang, humor and order modifications. Those are vendor descriptions of its platform, not independent performance benchmarks.
Yum’s 2024 announcement placed voice ordering within a broader drive-thru experience that also includes digital menu boards, its Poseidon point-of-sale system and Taco Bell Rewards. The 2025 NVIDIA announcement described a separate set of pilots involving NVIDIA Riva and NVIDIA NIM microservices, including voice agents, computer vision and restaurant analytics, alongside Yum’s Byte technology platform. The available announcements do not resolve how those initiatives relate technically to Omilia’s deployment.
The sources do not establish that AI takes every order at participating restaurants, whether a human handoff is available in every case, or how the system performs across locations. They also do not provide independently measured changes in order accuracy, wait times, customer satisfaction, staff retention or sales.

Why Taco Bell says it is using AI
Yum said its aims included easing team members’ task load, improving accuracy and consistency, reducing waits, supporting a friendly service experience and enabling profitable growth. Taco Bell’s then-Chief Digital & Technology Officer, Dane Mathews, said in the July 2024 announcement that AI could ease workloads and free staff to focus on front-of-house hospitality. These are company-stated goals, not demonstrated results.
Omilia’s case study says transaction times were on par with or better than human order taking, and describes early indicators of lower turnover and sales or transactions on par with or better than stores without AI. These are vendor-reported comparisons; the case study does not provide numerical effect sizes or establish that AI caused the outcomes. Yum’s 2024 release likewise included no quantified improvement.

What the reported problems mean for customers
Restaurant Dive’s account of the 2025 slowdown points to complaints and people deliberately abusing the order-taking system as obstacles to rollout. It does not quantify complaints, identify a particular failure rate or show that the system was withdrawn everywhere. In its July 2026 report, Restaurant Dive said Taco Bell remained committed to expanding voice AI and worked with multiple providers. Mathews described Omilia as proven at scale in select U.S. restaurants; that is Taco Bell’s endorsement, not an independent assessment.
For customers, the practical answer is that whether an order is handled by AI depends on the location. The reported footprint spans 38 states, but does not mean all restaurants in those states—or all Taco Bell drive-thrus nationwide—use it. The sources do not specify a universal method for requesting a human instead.
