Structure | Versions | Misc


Release Version 1.3 (19 August 2002)

This is final release of isolet corpus including transcriptions and time align phonetic transcriptions (automatic force alignment).

Release Version 1.2 (3 June 2002)

Several changes have been done to directory structure, adding statistics for number of speakers and files.

Release Version 1.1 (31 July 2000)

Several changes have been implemented that differentiate this version of the ISOLET Corpus from version 1.0. These changes include the following:
  • Speech files in the /speech directory have been converted from NIST format to RIFF format.
  • Individual transcription files have been extracted from the trans.txt file. These individual files have been placed in /trans directory which has a structure that exactly parallels that of the /speech directory.
  • The documentation has been updated so that it accurately reflects the corpus contents.
  • The corpus has been transferred to compact disc and is now available in that format.

These and other changes have been made to make the corpus more useful to the end-user.

Release Version 1.0 (July 1996)

First release. Contains all of the data. This corpus is distributed on DAT tape for either UNIX-based workstations or Windows PCs.
