We have previously presented HALEF-an open-source spoken dialog system-that supports telephonic interfaces and has a distributed architecture.In this paper, we extend this infrastructure to be cloud-based, and thus truly distributed and scalable.This cloud-based spoken dialog system can be accessed both via telephone interfaces as well as through web clients with WebRTC/HTML5 integration, allowing in-browser access to potentially multimodal dialog applications.We demonstrate the versatility of the system with two conversation applications in the educational domain.
