Foreword This Technical Specification (TS) has been produced by Joint Technical Committee (JTC) Broadcast of the European Broadcasting Union (EBU), Comit Europen de Normalisation ELECtrotechnique (CENELEC) and the European Telecommunications Standards
24、Institute (ETSI). NOTE 1: The EBU/ETSI JTC Broadcast was established in 1990 to co-ordinate the drafting of standards in the specific field of broadcasting and related fields. Since 1995 the JTC Broadcast became a tripartite body by including in the Memorandum of Understanding also CENELEC, which is
25、 responsible for the standardization of radio and television receivers. The EBU is a professional association of broadcasting organizations whose work includes the co-ordination of its members activities in the technical, legal, programme-making and programme-exchange domains. The EBU has active mem
26、bers in about 60 countries in the European broadcasting area; its headquarters is in Geneva. European Broadcasting Union CH-1218 GRAND SACONNEX (Geneva) Switzerland Tel: +41 22 717 21 11 Fax: +41 22 717 24 81 The Eureka Project 147 was established in 1987, with funding from the European Commission,
27、to develop a system for the broadcasting of audio and data to fixed, portable or mobile receivers. Their work resulted in the publication of European Standard, EN 300 401 13, for DAB (see note 2) which now has worldwide acceptance. The members of the Eureka Project 147 are drawn from broadcasting or
28、ganizations and telecommunication providers together with companies from the professional and consumer electronics industry. NOTE 2: DAB is a registered trademark owned by one of the Eureka Project 147 partners. Introduction The Broadcast WebSite (BWS) specification 1 defines a mechanism to format a
29、nd transfer Web-like applications in the context of DAB. The BWS application is a relatively basic implementation of typical Web applications since it only offers a limited number of the usual capabilities. Recent developments in mobile hardware have brought many new possibilities and further improv
30、ements in mobile devices can be expected for many years to come. These new capabilities could be used to provide a better and more complete user experience. In the case of the current BWS application, it is not well adapted to some mobility cases where the user is doing other things while using the
31、system such as driving a car or crossing the street. Since BWS is mainly driven by a visual interface, safety and convenience in mobile environments could become important issues. A more adapted system could thus be created to fill the lack of features of the old BWS system. The voice interface offe
32、red by new mobile devices could be used in the creation of new and enhanced services. Moreover, a new set of applications could be introduced to provide increased usability and user friendliness. ETSI ETSI TS 102 632 V1.1.1 (2008-11)71 Scope The present document describes Voice Applications specific
33、ation. To begin with, the VoiceXML profile is explained with details about the modularization of VoiceXML 2.0, the dialog constructs, the user input, the system output, the control flow and scripting and the environment and resources. Then, the synchronization management mechanism is explained, foll
34、owed by the specification of the extended interfaces. Finally, the transport and signalling of Voice Applications are detailed. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequen
35、t 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 accepted that it will be possible to use all future changes of the referenced document for the purposes of the referring document; - for informative
