ACL-02 Workshop on Speech-to-Speech Translation: Algorithms and Systems July 11 2002 University of Pennsylvania, Philadelphia A workshop held as part of the Association for Computational Linguistics 40th anniversary meeting ACL-02 (http://www.acl02.org) Hosted by The Computer and Information Science Department and the Institute for Research in Cognitive Science University of Pennsylvania, Philadelphia July 7-12 2002 CALL FOR PAPERS DESCRIPTION: Facilitation of speech communication across language barriers is a critical problem to solve for a global economy to thrive. Robust systems for speech-to-speech translation (S2S) are clearly necessary to move us towards achieving this goal. However, construction of such systems is clearly extremely complex, involving research in Automatic Speech Recognition(ASR), Text-to-Speech (TTS), Machine Translation (MT), Natural Language Understanding (NLU) and Generation (NLG). Although substantial progress in each of these components individually has been made over the last two decades, simply integrating individual ASR, NLU, MT, NLG, and TTS components to produce S2S systems is not sufficient to produce acceptable results. For example, conventional text-based MT systems have not been designed to cope with the imperfect syntax and transcription errors which characterize automatically transcribed conversational speech. Traditional speech recognizers (ASR component) and speech synthesizers (TTS component) have not been designed to recognize or synthesize speakers' emotional expressions which convey meanings and play an important role in the communications between human beings. Therefore, speech-to-speech translation raises a whole new set of algorithmic challenges over and above those associated with the individual underlying technologies themselves. We would like to bring together various researchers in the field together to present the current state-of-the-art on speech-to-speech translation and discuss the challenges involved in building a functioning high performance system. We hope to hear about different approaches to the S2S realization and exchange ideas about the advantages and disadvantages of various approaches. The workshop will specifically focus on natural language processing problems which are unique and critical to producing robust speech-to-speech translation systems and components. We solicit submissions to the workshop in the following areas, however any other topic related to the speech-to-speech translation is also acceptable: Machine Translation: - Algorithms for machine translation applicable to S2S - Algorithms and systems for application specific and limited dom ain machine translation - Rule-based MT, statistical MT, template-based MT, interlingua-b ased MT Speech recognition and TTS: - Enhancing the performance of ASR in S2S using natural language processing techniques - TTS modules with highly naturalness and emotional expressions - Robust speech recognition algorithms for S2S - Challenges for extracting and conveying stress, prosody and emo tions in speech across languages NLP: - Natural language processing algorithms for S2S - Natural language generation from meaning representations Language: - Challenges for speech-to-speech translation across languages du e to language characteristics, and suggestion of solutions - Challenges for conveying stress, prosody and emotions in speech across languages System architecture and software integration - Component architecture and design of modular S2S systems - Portability of S2S systems to different languages and domains - Implementation issues for robust and limited resource S2S systems Multilingual Data Collection and System Evaluation: - Evaluation metrics of spoken language translation quality - Language resources and knowledge acquisition SUBMISSIONS: We invite paper submissions from all researchers in the area of S2S translation, natural language processing, linguistics, and all related topics. All submissions will be reviewed by an international program committee. If sufficiently many high-quality papers are submitted, we will consider publishing selected papers in an edited volume. Submissions should follow the two-column format of ACL proceedings and should not exceed eight (8) pages, including references. We recommend the use of ACL LaTeX style files or Microsoft Word Style files available at: http://www.c s.ualberta.ca/%7Elindek/acl02/style/. Deadline for paper submissions is March 15, 2002. Papers in pdf format must be submitted electronically to: yuqing_(on)_us.ibm.com. WORKSHOPS REGISTRATION FEES: The duration of the workshop is one full day. Only ACL-02 conference participants are allowed to register for the workshop. The registration fee is going to be set by the ACL-02 organizing committee. The Proceedings of the Workshop will be published by the ACL-02 organizing committee.
