This paper presents a set of information and communication technologies developed with the goal to improve the learning and practice of Cued Speech. They are based on 3D graphics and are covering the entire end-to-end content chain: production, transmission and visualization. Starting from the requirements of an online system for Cued Speech, the research and development path took into account real-time constraints, personalization, user acceptability and equally important, the easiness and feasibility of the deployment, hence a strong orientation towards open standards. The original components of the system include 3D graphics and animation encoders, streaming servers and visualization engines. We validated them in two applications: a web service for text to animation conversion and a chat service supporting two or more users
