OpenAI has released an open-source React component library, realtime-voice-component, designed to integrate voice control into web applications. Built on OpenAI's Realtime API, the library allows users to control app functions through voice commands using the gpt-realtime-1.5 model. Developers can register app actions as voice tools and manage session lifecycles, enhancing user interaction with features like GhostCursorOverlay for visual feedback. The library serves as a reference and educational tool, with a demo showcasing theme switching, multi-step forms, and chess gameplay scenarios.
