| Abstract;The rapid growth of broadband connections is providing an environment conducive to high-quality voice communications. Nevertheless, to achieve sophisticated voice services to replace conventional telephone calls, a variety of bandwidth capacities and sound-reproduction environments must be supported. Here, we introduce a scalable speech coding technique that enables flexible sound quality reproduction. Utilizing the hierarchical nature of scalable coding, we created a flexible-design policy that has a high affinity with network control technology and enables us to design and build applications that can be used in various scenarios.
