                              (IWSLT 2014)

First Call for Participation

December 4-5, 2014
     Lake Tahoe, CA, USA

The International Workshop on Spoken Language Translation (IWSLT) is an
annual scientific workshop, associated with an open evaluation campaign
on spoken language translation, at which both, scientific papers and
system descriptions, are presented. The 11th International Workshop on
Spoken Language Translation will take place in Lake Tahoe, USA on
December 4-5, 2014. IWSLT 2014 is co-located with SLT 2014, which will
take place right after IWSLT.

=== Evaluation Campaign ===

The IWSLT 2014 Evaluation Campaign will focus on the translation of TED
and TEDx talks, a collection of public speeches on a variety of
topics. The evaluation campaign will include the following tracks:

ASR track: automatic transcription of talks from audio to text, 
English, German and Italian

SLT track: speech translation of talks from audio (or ASR output) to
Input format: segmented SPHERE or ASR output
* Official: English -> French, German <-> English, Italian <-> English
* Optional: English -> Arabic, Chinese

MT track : text translation of talks for three language pairs plus 
twelve optional language
pairs Directions:
* Official: English -> French, English <-> German, Italian
* Optional: English <-> Arabic, Chinese, Dutch, Hebrew, Persian, 
Polish, Portuguese (B),
   Romanian, Russian, Slovenian, Spanish, Turkish

Evaluation methods:
ASR track: word or character error rate
SLT/MT: BLEU (all directions) and post-edit effort (most popular
official direction)

Training of MT systems and language models for ASR is constrained to
data supplied by the organizers. Supplied training, development, and
test data will be available on the workshop’s webpage.

=== Scientific Papers ===

The IWSLT invites submissions of scientific papers to be published in
the workshop proceedings and presented in dedicated technical sessions
of the workshop, either in oral or poster form. The workshop welcomes
original and high quality contri- butions covering theoretical and
practical issues in the fields of automatic speech recognition and
machine translation that are applied to spoken language
translation. Possible topics include, but are not limited to:

- Speech and text MT
- Integration of ASR and MT
- Statistical modeling for MT and SLT
- Evaluation for MT and SLT
- Adaptation in SLT
- Simultaneous speech translation
- Computer assisted speech translation
- Automatic translation of lectures
- Efficient computational architectures for SLT
- SLT for under-resourced languages
- Spoken language summarization
- Rich transcription of speech for MT
- Stream-based algorithms for MT
- Multilingual ASR and TTS
- Cross-lingual spoken document retrieval
- Multi-lingual spoken language mining
- Translation of non-verbal events
- Speech-to-speech translation
- Language resources for MT and SLT
- Open source software for MT and SLT
