Dairy Queen expands drive-thru voice AI pilot to franchisees across North America

Dairy Queen’s new voice AI push is not just about a smoother drive-thru. It is about which pieces of a busy shift get handed to a machine, and which tasks still land on the crew when a customer has a custom order, a noisy car, or a system error.

On April 16, American Dairy Queen Corp. said it had partnered with Presto to expand voice AI ordering beyond company-operated stores to select franchisees across the United States and Canadian provinces. Presto and Dairy Queen said the rollout would reach at least 25 franchisees across at least 25 states and provinces, with expansion starting in phases over the next few weeks. The long-term target is even larger: substantially all of Dairy Queen’s roughly 3,000 drive-thrus in North America.

For line employees and shift managers, the practical change is less about robots replacing a restaurant and more about changing the shape of the work. The system is designed to take orders and handle customer interactions, which means fewer minutes on the headset for some crew members and more time on food prep, packaging, handoff, expo work, and fixing problems when the AI mishears a customer. Dairy Queen says the technology is meant to improve order accuracy and help workers focus on higher-value tasks, while Presto says it is meant to increase revenue, reduce labor costs, improve staff productivity, and standardize the guest experience.

That labor-saving pitch lands differently in a franchised chain, where each operator feels staffing pressure in its own way. A franchisee short on labor may see voice AI as a way to stretch a skeleton crew through the lunch rush. A store already struggling with turnover may see it as one more system workers have to learn while still keeping cars moving. The machine may take the first pass at the order, but humans still have to catch the mistakes, calm irritated guests, and keep the line from backing up when the software stumbles.

The move also fits a wider fast-food pattern. McDonald’s ended its AI drive-thru test with IBM in 2024 after a pilot at more than 100 restaurants. Wendy’s has kept expanding FreshAI, and the company has said the system is intended to free team members for other work. Wendy’s public filing said FreshAI averaged an 86% success rate before team-member intervention. Intel’s case study on Lee’s Famous Recipe Chicken said Hi Auto handled more than 94% of orders on its own with 95% order accuracy, compared with an average human drive-thru accuracy rate of 84.4% cited in the same document.

Those numbers explain why chains keep testing voice ordering, and why workers should pay attention. The National Restaurant Association has said a meaningful share of operators plan to invest in AI, and Dairy Queen’s expansion shows the technology is moving from pilot novelty to franchise-level rollout. The real question on the restaurant floor is not whether the headset disappears, but how much of the shift gets reorganized around a system that still needs people when it gets it wrong.
