A global quick-service restaurant (QSR) chain is transforming its drive-thru operations by implementing Fireworks' real-time voice intelligence platform to enhance customer interactions and operational efficiency. The initiative aims to digitize order-taking entirely, enabling faster and more personalized service. Fireworks provides a unified platform delivering sub-500ms transcription latency, significantly reducing costs and improving accuracy even in noisy environments. This solution has demonstrated success with a rapid pilot-to-production rollout, showing a 3-5 times return on investment in initial stores and plans to scale across over 6,000 locations. This strategic partnership, validated through technical benchmarking against competitors like OpenAI and Whisper, positions the brand to leverage voice AI for smarter upselling and enhanced customer satisfaction. Future plans include expanding Fireworks' capabilities to voice agents and analytics, supporting the QSR's vision for a fully digital drive-thru experience.
