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 the recordings of around 283 hours from EPPS (European Parliament Plenary Sessions) speeches held or interpreted in European Spanish (a mixture of native and non-native Spanish), 62 hours of which were annotated (transcribed) within the project (the transcriptions are not provided in the present package but will be made available soon). These recordings were obtained from Europe by Satellite (http://europa.eu.it/comm/ebs) from May 2004 until May 2006. 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.
