6、nctional requirements for network-based speech-to-speech translation services Summary Recommendation ITU-T F.745 specifies a high level functional model, a service description and requirements for speech-to-speech translation (S2ST) accomplished by connecting distributed S2ST modules all over the wo
7、rld through a network. To extend this network-based S2ST to other modalities, such as sign language, the modality conversion markup language (MCML) needs to have an expandable structure. The scope of this Recommendation is limited to the application protocol and the services using the network-based
8、S2ST. This revision includes additional information to clarify that Recommendation ITU-T F.745 could be applicable to both face-to-face communication and remote communication.

ITU-T F.745 (07/2016) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, info
11、rmation and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a wo
12、rldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in
13、 WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication admi
14、nistration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory pro
15、visions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention
16、to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outs
17、ide of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the la
18、test information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T/ipr/. ITU 2016 All rights reserved.

ITU-T F.745 (07/2016) Introduction The fact that the world has many different languages is one of the barriers to mutual understanding. The more directly people who speak different langua
23、ges can communicate without language boundaries, the more mutual understanding can be accelerated and the closer human relationships can be constructed all over the world. To achieve such communication between humans, speech-to-speech translation (S2ST) technologies can be used. S2ST is a technology
24、 that recognizes the speech in one language, translates the recognized speech into another language, and then synthesizes the translation into speech. The leveraging of S2ST technologies in a pragmatic manner, which has long been one of mankinds dreams, may have a significant impact on tourism, soci
