[Mt-list] TC-STAR Third Evaluation Campaign 2007 - Call for Participation

[ELDA]

TC-STAR Third Evaluation Campaign 2007 Call for Participation 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 outside participants in its 3rd evaluation of January-February 2007. This participation is free of charge.
