Speech coders are used to transmit and store speech in digital form for various applications. This paper describes how to set requirements for given applications, the interactions between research and business units, and the role that standards bodies play. Creating a coder that meets the requirements of its customers and dealing with the issues involved in implementing the coder are an integral part of the development process. After the development is complete, the speech coder must be integrated into a product. As an example, the design and integration of the AUDIX® voice messaging coder (VMC) are described. The future holds ever-increasing challenges and new technology in which speech coders will play an integral role.
