Each release of transcription data for this project will be a superset of the previous release (in other words, you need only download the latest release). All transcriptions and segmentations developed in this project are based on the audio data from the following SWITCHBOARD release:

Switchboard-1 Telephone Speech Corpus: Release 2 August, 1997

For information regarding SWITCHBOARD, please consult the LDC web site. For more details about this project, see the project overview. A mailing list is also available to discuss progress and key issues of the project.
