Introduction

This publication contains the Speech in Noisy Environments (SPINE) Training Transcripts, created for the Department of Defense (DoD) Digital Voice Processing Consortium (DDVPC) by Arcon Corp., and produced by the Linguistic Data Consortium (LDC) catalog number LDC2000T49 and ISBN 1-58563-174-4. A companion corpus, Speech in Noisy Environments (SPINE) Training Audio, was also produced by the Linguistic Data Consortium (LDC); catalog number LDC2000S87, ISBN 1-58563-173-6. These corpora support the 2000 Speech in Noisy Environments evaluation. For an example transcript, please click here.

The 2000 Speech in Noisy Environments Evaluation (SPINE1) is a first attempt to assess the state of the art and practice in speech recognition technology in noisy military environments and to exchange information on innovative speech recognition technology in the context of fully implemented systems that perform realistic tasks. It is intended to be of interest to all university, industrial and commercial speech system developers working on the problem of robust speech recognition. The evaluation gives participants the opportunity to participate in a flexible evaluation, suited to development needs and abilities.

The SPINE1 evaluation focuses on the task of transcribing speech produced in noisy environments with the emphasis on speech produced in noisy military environments. The evaluation is designed to promote research progress in this area, to provide the opportunity for participants to try out new ideas for developing robust speech recognition systems that are of both scientific and practical interest, and to measure the performance of this technology. More information on this evaluation is available at SPINE1.

This work was sponsored in part by National Science Foundation Grant No. IIS-9982201.

Data

The evaluation task is to transcribe speech produced in noisy environments. The training and test speech data to be used for this evaluation were generated by ARCON Corp. for the DoD Digital Voice Processing Consortium (DDVPC) under controlled conditions. The speech data consists of conversations between two communicators working on a collaborative, Battleship-like task in which they seek and shoot at targets (ARCON Communicability Exercise, ACE). Participants may talk freely, but the total vocabulary used is fairly limited. Each person is seated in a sound chamber in which a previously recorded military background noise environment is accurately reproduced. The participants use handsets and transmission channels that are resident to the particular environment. The training data includes 10 of 20 available talker pairs with 14 five-minute conversations per talker pair (about 720 minutes total) available, which include four noise scenarios.
