Drive-thru crews talk less at the window when voice AI takes the order

The 2026 QSR Drive-Thru Report, which QSR Magazine publishes with its data partner Intouch Insight, finds that within the voice AI encounters shoppers logged, the technology did more of the work in 2026, and order accuracy increased.

For an operations leader deciding how far to push voice ordering, the report moves the next problem down the lane. The AI is getting better at its job. The crew's job after the AI hasn't been redefined yet.

Twice the orders, same footprint

Intouch sent shoppers to targeted locations at three brands confirmed to use AI ordering, Burger King, Taco Bell and Wendy's, and they logged 95 AI interactions. Another 79 came from shoppers who ran into voice AI without looking for it, and that brought McDonald's into the sample. Sarah Beckett, Intouch's VP of sales and marketing, told QSR Magazine the biggest change was what the technology can do once a guest is talking to it. Where it's being used changed much less.

The numbers bear that out. AI handled the full order in 40% of encounters, up from 20%. Visits where the AI only said hello and then passed the guest to an employee fell from 70% to 50%.

In Beckett's view, the past year has not brought a wide jump in the number of places using voice AI. What has improved is how much the system can handle once it is engaged. Taco Bell said in July that its automated voice ordering now runs in nearly 900 U.S. stores in 38 states, a rollout of about three years carried out under its growing partnership with Omilia, QSR Magazine reported. Put together, this year's story centers less on reach than on how the AI performs after a guest encounters it.

Guests have noticed only part of that improvement. Beckett's read is that the AI is completing more transactions, but that hasn't yet made the experience consistently smoother.

The window goes quiet

The pattern at the window is specific. When AI handled the ordering conversation, the behaviors that require a crew member to actively speak dropped sharply. Passive physical tasks held steady or rose slightly. QSR Magazine's reading is that crews treat the handoff as more transactional because the conversation has already happened with the machine. The magazine calls it a people-management issue amplified by technology, not an AI problem.

For operators, the window could matter more to how a visit feels once AI takes the order. QSR Magazine reports that behaviors requiring active verbal engagement declined sharply with an AI presence.

This matters beyond manners. Intouch added a friendliness section to this year's main study, tracking how friendliness moves with satisfaction, order accuracy, value perception and whether guests would recommend the brand. Separately, CACI research covered by QSR Media found that order accuracy and service quality matter more for repeat visits than speed alone. Some scorecards measure speed and accuracy at the speaker but not what's said at the window. For brands using those, an AI rollout could raise the numbers they track while the ones they don't track slip.

Greeter-only AI is the weak setup

Pricing the lane and the window

What year three would show

If they recover, coaching caught up on its own. If they don't, brands running voice ordering at scale could need a written window standard for cars whose order was taken by a machine.
