Information technology — User interfaces — Voice commands — Part 2: Constructing and testing
ISO 30122-2:2017 provides the technical criterions and test methods of voice commands and its speech recognition engine. The technical criterions include the phonetic requirements for spoken words or phrases that compose the voice command. The test methods verify whether the voice command or speech recognition engine satisfies the required specifications.

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. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
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 ISO documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not

Introduction
Voice command is used for controlling ICT devices with the voice and in the language of the user. This
technology is based on speech recognition, with some consideration for language tolerance (different
accents or speech impairment while using a given language). It is also beneficial to the people who are
operating the ICT device when/where they cannot use hands or fingers to operate it.
This document defines the principal standardized voice commands that will be commonly used in
various ICT devices.
