TC-STAR is a European integrated project focusing on all core technologies for Speech-to-Speech Translation (SST): Automatic Speech Recognition (ASR), Spoken Language Translation (SLT), and Text to Speech Synthesis (TTS).
This corpus consists of 70 hours of recordings of EPPS (European Parliament Plenary Sessions) speeches held or interpreted in European English and other European languages. From this corpus, 16 hours of English speeches (native or non native) were annotated (transcribed). Transcriptions are included in the present package. The data comprises the test (development and evaluation) data for the TC-STAR project in the years 2005, 2006, and 2007. The recordings were obtained from Europe by Satellite (http://europa.eu.it/comm/ebs) from Oct. until Nov. 2004, June to Nov. 2005, and June until July 2006. The transcription files are stored in Transcriber XML file format.
The speech signals were submitted by EbS via internet in Real Media format and via satellite in MPEG1-layer2 format. The signals were decoded, resampled and are stored in WAVE RIFF (Resource Interchange File Format). Each file contains a single channel with 16-bit resolution at a sample rate of 16kHz.
The speech databases made within the TC-STAR project were validated by SPEX, in the Netherlands, to assess their compliance with the TC-STAR format and content specifications.
