Case Study: White Castle achieves faster, more accurate drive-thru service with SoundHound AI

White Castle - Customer Case Study

White Castle, America’s first fast-food hamburger chain, faced mounting drive-thru pressure—overworked staff, longer wait times, order inaccuracy, and less face time with customers. To address this, White Castle partnered with SoundHound and deployed SoundHound’s AI voice assistant, Julia, to handle drive-thru ordering and free staff to focus on customer service.

SoundHound’s solution routes voice orders directly to the POS and kitchen, taking each order in under 60 seconds and delivering over a 90% order completion rate with no manual input. The implementation improved order accuracy, enabled 100% upsell consistency, reduced staff burnout and turnover, and increased repeat business and customer satisfaction.
