Your next drive-thru order might be taken by a bot. And you might not even notice.

Kristen Charpentier’s first hint that she was talking to a robot when she pulled into a Dairy Queen drive-thru lane was that the voice coming out to the speaker was, simply put, “too nice.”

“There was no communication delay or weirdness to it. It felt completely natural,” Charpentier tells WIRED. “But just a little too pleasant to be human.”

The voice punctuated its sentences with pleases and thank yous. It was soft and friendly. Its attempts to upsell Charpentier on extra Snickers for her Blizzard were perfectly polite.

But Charpentier worked the Dairy Queen drive-thru herself as a teenager. She knew something wasn’t adding up. When she drove up to collect her Blizzard at the window of the Cary, North Carolina, drive-thru, she asked the worker in the window: Had AI taken her order?

The employee confirmed to Charpentier that she was one of the thousands of customers across the US to have experienced an AI-voice-equipped drive-thru. In 2024, roughly 4 percent of fast-food locations in the US used voice AI technology in the drive-thru lane, according to Intouch Insight’s annual Drive Thru Survey. Last year, that figure grew to 5 percent; early research suggests that has now climbed to 6 percent.

For most of these customers, the first AI order comes as a surprise, one to be filmed and posted on TikTok or Snapchat. But soon, these automated ordering systems will seem downright banal. At certain chains, voice AI is already the new normal. Taco Bell announced in July that it has rolled out AI at 890 drive-thru lanes, more than 10 percent of the chain’s US locations. Dairy Queen is implementing the tech in 25 states, with eventual plans to roll it out to all restaurants. Twelve percent of White Castles use an AI named “Julia” in their drive-thrus; all new locations now open with Julia taking orders.
