Forewo
15、rd This ETSI Standard (ES) has been produced by ETSI Technical Committee Human Factors (HF). The work has been conducted in collaboration with industry. The present document is based upon user testing, empirical data, phonetic discriminability analysis, expert knowledge, and an industry-consultation
16、 and consensus process, aimed at a quick uptake and the widest possible support in product implementations to come. Intended readers of the present document are: terminal manufacturers; service providers; network operators; manufacturers of multilingual speech recognizers; standards developers; soft
17、ware and user interface developers. Introduction Telecommunications, converging with information processing, and intersecting with mobility and the internet, are leading to the development of new interactive applications and services, offering global access. A technology enabling a natural user inte
18、raction with these (often complex) systems and services is speech recognition. In recent years, speech recognition has become commercially viable in off-the-shelf ICT (Information and Communication Technology) devices and services. Just as the graphical user interface changed the way we interact wit
19、h personal computers, so voice user interfaces are changing the way we interact with ICT devices and services. Voice is fundamental to human communication and forms an important channel for universal access to ICT services. Voice user interfaces are a terminal, display and potentially location-indep
20、endent user interface technology, enabled by speech recognition technologies. In order to simplify the users learning and facilitate reuse of knowledge for the control of different applications and devices, it is desirable to standardize voice commands for the most common and generic functions. This
21、 standardization activity also meets one of the most important principles of the eEurope 2005 Action Plan; that of design for all. This theme has been continued by the new EU initiative; the i2010 Action Plan. This will help ensure that those with special needs such as elderly people, people with vi
22、sual and other impairments, as well as young children will benefit from a generic spoken command vocabulary. As the standard necessarily addresses speech input it is recommended that the users of the present document provide some form of guidance for those end users who may have a speech impediment.
23、 ETSI ETSI ES 202 076 V2.1.1 (2009-08) 5The present document is a timely contribution to enable the deployment of speech recognition in services and devices, offering multi-lingual voice user interfaces. Thereby it will minimize learning effort, facilitate knowledge transfer and develop user trust.
24、Uniformity in the basic spoken commands improves the overall usability of the entire interactive environment, which becomes increasingly important in a world of ubiquitous devices and services using speech recognition. The minimum generic set of spoken commands in the present document has been devel
25、oped with a combined methodology, including the collection of data from native speakers of the 30 languages covered by the present document (see annex A for details). Therefore, it supports developers of ICT devices and services, leading to quicker, more consistent, cheaper, and better user interfac
26、e development. The work is aligned with, and co-funded by, the European Commissions initiative eEurope, a programme for inclusive deployment of new, important, consumer-oriented technologies, opening up global access to communications and other new technologies, for all 2. ETSI ETSI ES 202 076 V2.1.
27、1 (2009-08) 61 Scope The present document specifies a minimum set of spoken commands required to control the generic and common functions of ICT devices and services that use speaker-independent speech recognition. It specifies the necessary and most common vocabularies for voice commands to be supp
28、orted by ICT devices and services. The present document is applicable to the functions required for user interface navigation, call handling, the control of and navigation in media, and management of device and service settings. The present document specifies commands for the official languages (at
29、the time of publication) of the European Union (EU) and the European Free Trade Association (EFTA) countries, and for Russian. The standard addresses Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Icelandic, Irish, Italian, Latvian, Lithuania
30、n, Macedonian, Maltese, Norwegian, Polish, Portuguese, Raeto-Romance, Romanian, Russian, Slovak, Slovene, Spanish, Swedish, and Turkish 4. Therefore, this updates the existing standard, ES 202 076 1, which covers only the five languages with the largest number of native speakers in the European Unio
31、n: English, French, German, Italian and Spanish. The present document does not cover dialects with the exception of Norwegian and Raeto Romance both of which have established dialects. All languages are addressed in “Received Pronunciation“. The present document does not cover dialogue design issues
32、, the full range of supplementary telecommunications services, performance-related issues or speech output. Alphanumeric characters and symbols are not covered with the exception of single digits and language-specific reference to two recurring digits (e.g. “Double Two“). 2 References References are
33、 either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only in the following cases: - if it is acce
