A digital teleconferencing system with integrated modalities for human/machine communication: HuMaNet

摘要

The design and implementation of a digital teleconferencing system that integrates a number of speech technologies together with image and data facilities is described. The aim is to provide a variety of sophisticated communication features that are easy to learn and use. The system is called HuMaNet, for human-machine network. The system is controlled totally and interactively hands-free by natural speech. The system combines the technologies of speech recognition, text synthesis, and talker verification with autodirective microphone arrays, image compression, data, and hypertext management to provide high-quality audio and image conferencing. The present public-switched transport capacity provides 2B+D, or two 64 kB/s circuit-switched channels (2B), and one 16 Kb/s packet-switched channel (D).
