Call For Papers


11th International Workshop on Spoken Language Translation

(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 Decem- ber 4-5, 2014. IWSLT 2014 is co-located with SLT 2014, which will take place right after IWSLT.

For full information see our website at

=== 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, Languages: English, German and Italian

SLT track: speech translation of talks from audio (or ASR output) to text
Input format: segmented SPHERE or ASR output
Directions: 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
