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
of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/
IEC Directives, Part 2 (see www.iso.org/directives or www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not
received notice of (a) patent(s) which may be required to implement this document. However, implementers
are cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held

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 (this document) 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 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.

1 Scope
This document provides the general description of real-time automatic simultaneous interpretation systems
designed to interoperate among different natural languages for spontaneous speech.
While traditional speech to speech machine 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 interpr
