    This corpus comprises spontaneous speech (elicited) from 849 speakers of different dialects, ages and various educational levels (420 males and 429 females), who uttered 40 different topics, recorded over 2 channels (Mic1: SHURE SM58; Mic2: Labtec Axis-002). Speech samples are stored as a sequence of 16-bit 44.1kHz WAV for a total of 208 hours of speech per channel. The total capacity of the data is 122.8 Gb.
    Each speaker read 15 items. Text files are stored in Unicode format. All data have been proofread manually.
    The transcriptions include non-speech markers (background noise, background speech, speaker sounds) as well as markers for mispronunciation, channel distortions, words left-out and duplicates.
    The corpus aims to be applied to the testing and telephone natural speech recognition system.
