Information technology. User interfaces. Full duplex speech interaction

Abstract

Speech interaction user interface has been widely used for industrial applications and daily services. For example, it can be applied to automatic customer service in the telecommunication industry as a part of interactive voice response system. From the view of communication, a speech interaction user interface can be recognized as a duplex based system which enables bidirectional communication. In early stage, speech interaction user interfaces for conventional dialogue system were generally half duplex based and were designed to be turn–oriented work mode. As the growing complexity and diversity of requirements of human-machine interaction, the turn–oriented speech interaction user interface has become unfit for a conversation between human and machine.

Nowadays, full duplex (FDX) techniques are used in the speech interaction user interface to support session–oriented conversation between human and machine. The most differences between turnoriented and session-oriented speech interaction are continuity and naturalness, which make great progress in various applications of speech interaction user interface, such as smart speaker, chatbot, intelligent assistant, etc
