Introduction

This CD-ROM contains previously unreleased isolated-word and spell-mode (spelled out words) speech data from the (D)ARPA Resource Management (RM1) Corpus. This data is based on a 600-word subset of the 991-word RM1 vocabulary and contains spoken and spelled words pertaining to the RM1 naval resource management task. This corpus was collected simultaneously as part of the RM1 Continuous Speech Corpus (NIST Speech Discs 2-1-2-4) and contains speech from the same sets of subjects used in RM1.

Data

The speech data has been segmented into separate spelled and spoken-word waveform files for each subject-word utterance. Time-aligned word and phonetic transcriptions have been generated automatically using forced recognition and are included. The time-aligned transcriptions employ the same format and phone set as the TIMIT Acoustic-Phonetic Continuous Speech Corpus (NIST Speech Disc 1-1). See the TIMIT CD-ROM companion booklet, NISTIR 4930, pp. 29-31, for a description of the phone set.

As with the continuous speech portion of RM1, this data is subsetted into speaker-independent and speaker-dependent partitions. These data sets are further partioned into training, development-test and evaluation-test subsets. See the "readme.doc" file in the top-level directory of the disc for more information about the data.

Texas Instruments recruited the subjects and collected the speech. The National Institute of Standards and Technology (NIST) segmented the waveforms, generated the time-aligned transcriptions and produced this CD-ROM.
