                                  CALL FOR PAPERS


    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

    Machine Translation:
    - Algorithms for machine translation applicable to S2S
    - Algorithms and systems for application specific and limited dom
    machine translation
    - Rule-based MT, statistical MT, template-based MT, interlingua-b
    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
    in speech across languages
    - Natural language processing algorithms for S2S
    - Natural language generation from meaning representations
    - 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
    Multilingual Data Collection and System Evaluation:
    - Evaluation metrics of spoken language translation quality
    - Language resources and knowledge acquisition


    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

    Deadline for paper submissions is March 15, 2002. Papers in pdf format
    must be submitted electronically to:


    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.
