Burger King is testing artificial intelligence headsets to monitor how staff speak to customers. The system is powered by OpenAI technology. It is designed to assess whether employees are friendly during interactions.

The headsets analyse conversations between staff and customers in real time. The aim is to measure tone and service quality. The company is using the trial to understand how AI can support customer service standards.

The move reflects wider interest in using artificial intelligence in the workplace. Companies in the service sector are exploring tools that track performance and improve customer experience. Burger King has not given further details about where or how long the trial will run.
