Burger King is taking a closer look at what happens in its drive-thru lanes, and it is doing so with artificial intelligence listening in.
The fast-food chain is piloting AI-powered employee headsets that analyze customer interactions and generate so-called “friendliness scores.”
The technology, currently live in 500 US locations, brings a familiar contact center practice into a physical service environment where speed, accuracy, and tone collide in real time.
The system, known as BK Assistant, includes an AI chatbot dubbed “Patty” that employees can speak to through their headsets.
Patty answers questions about food preparation, flags operational issues such as low stock levels, and analyzes drive-thru audio for hospitality cues.

It is these hospitality cues that have dominated headlines.
Indeed, according to the BBC, the system has been trained to recognize phrases including “please” and “thank you,” using them as signals of service quality.
From a CX perspective, the move mirrors the evolution of speech analytics and agent assist tools that have become commonplace in contact centers.
Those systems promise more consistent service and faster coaching loops, but they have also sparked concerns about over-monitoring and scripted interactions.
Burger King now finds itself navigating the same trade-offs, just with customers sitting in cars rather than on phone lines.
The company has emphasized that the technology is not intended to record conversations or assess individual employees. Instead, it says insights are aggregated at the team level.

Burger King also said it explored “using aggregated keywords, such as common hospitality phrases” to understand the service being delivered and to “recognize teams who deliver great hospitality.”
Addressing concerns about automation replacing human judgment, the company added:
