Ergonomics - Accessible design - Spoken instructions of consumer products (ISO 24551:2019)

EN-ISO 24551 specifies ergonomic requirements and recommendations for consumer product spoken instructions that are provided to guide users in the operation of a product and/or as a means of providing feedback to users about the status/state of a product. Such instructions can be used by persons with or without visual impairments, and are useful for users who have difficulty reading and/or cognitive impairments. The applicability of the requirements and recommendations described in this document does not depend on the language of the instructions or whether the instructions are provided via recorded human speech or synthesized speech from text. The requirements and recommendations in this document are applicable to conventional, stand-alone consumer products in general, whose function is limited by characteristics that prevent a user from attaching, installing or using assistive technology in order to use the product. They are not applicable to machines and equipment used for professional work. This document does not apply to products for which the instructional content and/or the means of presentation are specified in other standards (e.g. medical devices, fire alarms). It also does not provide recommendations or requirements for spoken instructions of Interactive Voice Response (IVR) systems or digital assistants on personal computers or similar devices

Ergonomie - Zugängliche Gestaltung - Sprachführung für Konsumgüter (ISO 24551:2019)

Dieses Dokument legt ergonomische Anforderungen an und Empfehlungen für eine Sprachführung für Konsumgüter fest, die bereitgestellt werden um Benutzer beim Gebrauch eines Produkts zu leiten und/oder als Mittel um Benutzern Rückmeldungen zum Status/Zustand eines Produkts bereitzustellen. Solche Anweisungen können von Personen mit oder ohne Schädigungen des Sehvermögens verwendet werden und sind für Benutzer mit Leseschwäche und/oder kognitiven Beeinträchtigungen nützlich.
Die Anwendbarkeit der in diesem Dokument beschriebenen Anforderungen und Empfehlungen hängt nicht von der Sprache der Anweisungen ab oder davon, ob die Anweisungen über aufgezeichnete menschliche Sprache oder synthetisierte Sprache aus Text bereitgestellt werden.
Die Anforderungen und Empfehlungen in diesem Dokument gelten für herkömmliche, eigenständige Konsumgüter im Allgemeinen, deren Funktion durch Merkmale eingeschränkt ist, die verhindern, dass ein Benutzer Assistenztechnologien zur Verwendung des Produkts anbringt, installiert oder verwendet. Sie gelten nicht für Maschinen und Einrichtungen, die für fachmännisches Arbeiten eingesetzt werden.
Dieses Dokument gilt nicht für Produkte, deren Anleitungstexte und/oder Darstellungsweisen in anderen Normen festgelegt sind (z. B. medizinische Geräte, Feuerwarngeräte). Des Weiteren enthält dieses Dokument keine Empfehlungen oder Anforderungen an die Sprachführung von Sprachdialogsystemen oder digitalen Assistenten auf PCs oder ähnlichen Geräten.
ANMERKUNG ISO 9241 154 enthält Empfehlungen oder Anforderungen für Sprachdialogsysteme.
Dieses Dokument trifft keine Festlegungen für eine Sprachausgabe von Systemen zur Text/Sprache-Umwandlung oder Sprachanleitungen, die anstelle von gedruckten Bedienungsanleitungen und unabhängig vom Produkt verwendet werden.

Ergonomie - Conception accessible - Instructions vocales de produits de consommation (ISO 24551:2019)

Le présent document spécifie des exigences et des recommandations ergonomiques pour les instructions orales des produits de consommation courante qui sont fournies pour guider les utilisateurs lors de l'utilisation d'un produit et/ou qui permettent de renseigner les utilisateurs sur le statut/l'état d'un produit.

Introduction
Consumer products, as defined in ISO 20282-1, include home electrical appliances, information and
telecommunication products, gas-heating equipment, toys, sanitary equipment, health-care products,
and cameras, some of which use spoken instructions.
These spoken instructions can assist product users regardless of age, including those with visual
impairments or moderate cognitive disorders that can cause reading difficulties, in using the product
correctly and safely. The spoken instructions are also helpful for some users who are not accustomed
to using the product. Therefore, the instructions should be designed so that they are easy to hear and
comprehend.
This document adopts the principles of accessible design given in ISO/IEC Guide 71 and amplified in
ISO/TR 22411.

Introduction
People conduct their daily lives surrounded by various consumer products. Consumer products,
as defined in ISO 20282-1, include home electrical appliances, information and telecommunication
products, gas-heating equipment, toys, sanitary equipment, health-care products, and cameras, some of
which use spoken instructions.
These spoken instructions can assist product users regardless of age, including those with visual
impairments or moderate cognitive disorders such as difficulty in reading, in using the product
correctly and safely. The spoken instructions are also helpful for some users who are not accustomed
to use the product. Therefore, the instructions should be designed so that they are easy to hear and
comprehend by meeting users’ needs.
This International Standard specifies ergonomic requirements and recommendations of spoken
instructions that provide guidance for the user to use consumer products correctly and safely and,
thereby, enhance accessibility of the products for all users with various accessibility needs.
This International Standard adopts the principles of accessible design given in ISO/IEC Guide 71 and
amplified in ISO/TR 22411.

Ergonomics — Accessible design — Spoken instructions of
consumer products
1 Scope
This International Standard specifies ergonomic requirements and recommendations of spoken
instructions for consumer products that are used as a means of instructions for operations or feedback
of the status of products when used by a person with or without visual impairments.
NOTE 1 Spoken instructions are also useful for some users who have difficulty in reading and those with
cognitive impairment.
The requirements and recommendations described in this standard do not depend on the language of
guides and are applicable to conventional, stand-alone consumer products in general whose function is
limited by characteristics that prevent the user from attaching, installing or using assistive technology.
They are not applied to machines and equipment used for professional work.
This document is applicable to spoken instructions of both recorded human speech and synthesized
speech from text.
This document does not apply to products for which the instructional content and/or the means of
presentation are regulated by law or specified in other standards (e.g. medical devices, fire alarms). It
also does not provide recommendations or requirements for spoken instructions of Interactive Voice
Response (IVR) systems or digital assistants on personal computers or similar devices.
NOTE 2 ISO 9241-154 provides recommendations or requirements for IVR systems.
NOTE 3 ISO/TS 9241-126 provides generic guidance for the auditory presentation of information in interactive
systems.
This document does not specify voice sounds of text-to-speech systems or narrative speech used in
place of printed instruction manuals and independently from the product.
