Specialist Task Force 326: Generic spoken command vocabulary for ICT
devices and services (official EU and EFTA languages)
Who we are:
Team Leader: Michael Tate
Team Members: Rosemary Orr
What we do :
This EC/EFTA funded Specialist Task Force (STF 326) will produce the
following ETSI Standard:
Draft ETSI ES 202 076: Human Factors (HF); User
Interfaces; Generic spoken command vocabulary for ICT devices and services
Your input to and comments on our draft are welcome!
The new ETSI Standard will specify a minimum set of spoken
commands required to control the generic and most common functions of ICT
devices and services that use speech recognition,. These functions include
command, control and editing and will be applicable to the functions required
for navigation, information retrieval, basic call handling and configuration of
preferences. The ETSI Standard will also cover the most common telecommunication
services but it will not address user interface and dialogue design
issues, speech applications, the full range of supplementary telecommunications
services, performance related issues or speech output.
This new ETSI Standard will replace the
previous one ,
covering only five languages. Considering the expansion of the EU, a revision of
the Standard is necessary and includes 30 languages covering:
Official EU languages (members and candidates)
The aim is to simplify the use of the spoken interface by
choosing command words that users would use spontaneously say in various
situations. The project uses therefore a method which consists of the following
1. Conduct interviews in order to collect a set of
potential words by presenting various scenarios and ask the users which word
they would in the described situation. Interviews will take place with a great
number of native speakers covering the 30 languages and representing a wide
range of user categories.
2. Analyse the set of collected words and analyse the
frequencies of the words suggested by the interviewees.
3. Test of acoustic discrimination is necessary to avoid
the choice of words that are too similar, leading to a risk that users would be
misunderstood by the systems.
The STF will review the specified set of 70 common commands used in the
first standard and may also include additional commands.
Why we do it:
Speech recognition is a technology enabling the most
natural user interaction. In recent years, speech recognition has become
commercially available and viable in off-the-shelf products and services.
In order to simplify the user's learning procedure and
enable reuse of knowledge between different applications and devices, it is
highly desirable to standardize the most common and generic navigation, command
and editing vocabularies. All users could benefit from these spoken commands, in
particular those who are in a “busy hands situation” (e.g. driving a car, or
working with the hands) and the disabled (e.g. the visually impaired or blind).
The availability of a spoken command vocabulary in
all European languages is considered necessary, in order to cover user needs in
the enlarged EU, with regard to its cultural diversity. This benefits not only
the consumer but also the society and its cultural diversity, taking another
step towards the achievement of the goals set by the European Commission in the
eEurope 2005 Action Plan.
Currently, the ETSI Standard 202 076
specifies user tested spoken commands only for the five languages with the
largest number of native speakers in the European Union (English, French,
German, Italian and Spanish, as spoken in their respective countries).
Considering the expansion of the EU, a
revision of the ETSI Standard has been initiated by this project, in order to
provide similar support for all official European languages (including near-term
enlargement candidate countries and the official languages of the EFTA countries
