TC-STAR is an European integrated project focusing on Speech-to-Speech
Translation (SST). To encourage significant advances in all SST technologies,
annual competitive evaluations are organized. Automatic Speech Recognition
(ASR), Spoken Language Translation (SLT) and Text-To-Speech (TTS) are evaluated
independently and within an end-to-end system. The project targets a selection
of unconstrained conversational speech domains—speeches and broadcast news—and three languages: European English, European Spanish, and Mandarin Chinese.
The second evaluation campaign took place in March 2006 and was concluded by an international workshop. TC-STAR welcomes external participants in its 3rd evaluation of January-February 2007. This participation is free of charge.
The TC-STAR 2007 evaluation campaign will consider:
SLT in the following directions
a) Chinese-to-English (Broadcast News)
b) Spanish-to-English (European Parliament plenary speeches; Cortes Spanish Parliament speeches)
c) English-to-Spanish (European Parliament plenary speeches)
The SLT evaluation of European Parliament plenary speeches will cover three types of input:
1. ASR output (single best sentence, and more: N-best, word lattices)
2. verbatim transcription,
3. final text edition.
ASR in the following languages
TTS in Chinese, English, and Spanish under the following conditions:
a) English (European Parliament plenary speeches)
b) Spanish (European Parliament plenary speeches; Cortes Spanish Parliament speeches)
c) Mandarin Chinese (Broadcast News)
a) Complete system: participants use their own training data
b) Voice conversion intralingual and crosslingual, expressive speech: data provided by TC-STAR
c) Component evaluation
For ASR and SLT, training data will be made available by the TC-STAR project for English and Spanish and can be purchased at LDC for Chinese. Development data will be provided by the TC-STAR project. Legal issues regarding the data will be detailed in the 2nd Call For Participation.
The participation is free of charge and training/development/evaluation data from TC-STAR will also be made freely available to participants."
All participants will be given the opportunity to present and discuss their results in the 3rd TC-STAR evaluation workshop in Aachen in March 2007.
