Building AI with MongoDB: Giving Your Apps a Voice` explores how generative AI and MongoDB are being used to unlock value from data of any modality, supercharging communications through the power of voice technology. Voice brings context, depth, and emotion in ways that text, images, and video alone cannot, and its transformative journey spans over a century, from radio and telephone communication to cutting-edge generative AI. The post features three companies harnessing the power of voice with generative AI: Xoltar, Cognigy, and Artificial Nerds, highlighting their applications in patient engagement, conversational AI platform, and custom voice bots without complexity. MongoDB powers these applications through its flexible document model, event-driven data pipelines, and Atlas Search and Vector Search capabilities, enabling the companies to build new classes of user experiences and achieve real behavioral changes.
