The database comprises 16,499 short messages (SMS). Speech samples are stored as a sequence of 16-bit 22.05kHz WAV for 21.7 hours of speech. The total capacity of the data is 3.2 Gb.
    Each speaker read 120-150 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.
