This file contains documentation on the MDE RT-04 Training Data Speech, Linguistic Data Consortium (LDC) catalog number LDC2005S16 and ISBN 1-58563-355-0.
This corpus was created by Linguistic Data Consortium to provide training data for the RT-04 Fall Metadata Extraction (MDE) Evaluation, part of the DARPA EARS (Efficient, Affordable, Reusable Speech-to-Text) Program. This data set has been created and distributed by Linguistic Data Consortium. This data was previously released to the EARS MDE community as LDC2004E31.
The goal of MDE is to enable technology that can take raw Speech-to-Text output and refine it into forms that are of more use to humans and to downstream automatic processes. In simple terms, this means the creation of automatic transcripts that are maximally readable. This readability might be achieved in a number of ways: flagging non-content words like filled pauses and discourse markers for optional removal; marking sections of disfluent speech; and creating boundaries between natural breakpoints in the flow of speech so that each sentence or other meaningful unit of speech might be presented on a separate line within the resulting transcript. Natural capitalization, punctuation and standardized spelling, plus sensible conventions for representing speaker turns and identity are further elements in the readable transcript. LDC has defined a SimpleMDE annotation task specification and has annotated English telephone and broadcast news data to provide training data for MDE.
Samples For an example of the data in this publication, please review this broadcast news sample and this telephone conversation sample.
