Information technology — User interfaces for automatic simultaneous interpretation systems — Part 2: Requirements and functional description
This document provides user interface requirements and functional description of real-time automatic simultaneous interpretation systems designed to interoperate among different natural languages for spontaneous speech. While traditional speech to speech translation addresses the functional equivalent of consecutive interpretation, this document focuses on the functional equivalent of simultaneous interpretation. This document does not cover sign language interpretation.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations,
governmental and non-governmental, in liaison with ISO and IEC, also take part in the work.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types

Introduction
Communication between users of different languages is a global trend that is increasing. Real-time, automatic
simultaneous interpretation is needed for different applications such as video calls, live lecture translation
and wearable translation devices. Market demands for real-time automatic simultaneous interpretation
of free-style continuous utterances in the travel sector, global event management, phone calls, lectures or
meetings are also increasing. A standardized user interface (UI) for automatic simultaneous interpretation
systems fulfils these different needs for communication.
The ISO/IEC 23773 series consists of the following parts:
ISO/IEC 23773-1 provides a general description of automatic simultaneous interpretation systems designed
to interoperate among different natural languages for spontaneous speech and texts.
ISO/IEC 23773-2 (this document) provides the requirements and functional components for the UI of
automatic simultaneous interpretation systems.
ISO/IEC 23773-3 provides a reference architecture for automatic simultaneous interpretation systems
including functional modules and communication interfaces in a high-level approach.

Requirements and functional description
1 Scope
This document provides user interface requirements and functional description of real-time automatic
simultaneous interpretation systems designed to interoperate among different natural languages for
spontaneous speech.
While traditional speech to speech translation addresses the functional equivalent of consecutive
interpretation, this document focuses on the functional equivalent of simultaneous interpretation.
This document does not cover sign language interpretation.
