# This six-cdrom set contains all the audio data recorded from Voice of # America Mandarin Chinese broadcasts for the TDT2 Corpus. You should find # in the top level directory an index.html file as well as doc/ and sph/ # subdirectories. The doc/ subdirectory contains additional documentation. # The sph/ subdirectory contains the audio files. The contents of the CDs # are shown below. # # There are a total of 177 audio files in this collection, corresponding # to the 177 text streams (created by manual annotation of these files) # in the TDT2 text corpus. # # All audio files are in NIST SPHERE format (1024-byte ascii-formated # header), and the audio data have all been compressed using the # "shorten" algorithm developed by Tony Robinson at Cambridge University # (as implemented in the NIST SPHERE "w_encode" utility). Both the NIST # "w_decode" utility and the stand-alone "shorten" program from # Cambridge University can be used to uncompress the speech data. # # The collection period spans from Feb. 26, 1998 through June 30, 1998. # Files collected through April 3 are generally 60 minutes in length, # whereas files collected after that date range between 10 and 15 # minutes each. # # As with the file names in the TDT2 Text Corpus, the file names # assigned to the audio data indicate the date and time-span for each # recording, as follows: # # YYYYMMDD_STTM_ENTM_VOA_MAN.sph # # where "STTM" and "ENTM" are start and end times, respectively, on a # 24-hour clock (e.g. "0900" refers to 9:00 AM). # # # 189 files # 3.7 Gbytes tdt2_man_audio_1/index.html tdt2_man_audio_1/doc/file.tbl
