The DARPA Resource Management Continuous Speech Corpora (RM) consists of digitized and transcribed speech for use in designing and evaluating continuous speech recognition systems. There are two main sections, often referred to as RM1 and RM2. RM1 contains three sections, Speaker-Dependent (SD) training data, Speaker-Independent (SI) training data and test and evaluation data. RM2 has an additional and larger SD data set, including test material.
All RM material consists of read sentences modeled after a naval resource management task. The complete corpus contains over 25,000 utterances from more than 160 speakers representing a variety of American dialects. The material was recorded at 16KHz, with 16-bit resolution, using a Sennheiser HMD-414 headset microphone. All discs conform to the ISO-9660 data format.
Resource Managment SD and SI Training and Test Data (RM1)
The Speaker-Dependent (SD) Training Data contains 12 subjects, each reading a set of 600 "training sentences," two "dialect" sentences and ten "rapid adaptation" sentences, for a total of 7,344 recorded sentence utterances. The 600 sentences designated as training cover 97 of the lexical items in the corpus.
The Speaker-Independent (SI) Training Data contains 80 speakers, each reading two "dialect" sentences plus 40 sentences from the Resource Management text corpus, for a total of 3,360 recorded sentence utterances. Any given sentence from a set of 1,600 Resource Management sentence texts was recorded by two subjects, while no sentence was read twice by the same subject.
RM1 contains all SD and SI system test material used in five DARPA benchmark tests conducted in March and October of 1987, June 1988, and February and October 1989, along with scoring and diagnostic software and documentation for those tests. Documentation is also provided outlining use of the Resource Management training and test material at CMU in development of the SPHINX system. Example output and scored results for state-of-the-art speaker-dependent and speaker-independent systems (i.e. the BBN BYBLOS and CMU SPHINX systems) for the October 1989 benchmark tests are included.
Extended Resource Management Speaker-Dependent Corpus (RM2)
This set forms a speaker-dependent extension to the Resource Management (RM1) corpus. The corpus consists of a total of 10,508 sentence utterances (two male and two female speakers each speaking 2,652 sentence texts). These include the 600 "standard" Resource Management speaker-dependent training sentences, two dialect calibration sentences, ten rapid adaptation sentences, 1,800 newly-generated extended training sentences, 120 newly-generated development-test sentences and 120 newly-generated evaluation-test sentences. The evaluation-test material on this disc was used as the test set for the June 1990 DARPA SLS Resource Management Benchmark Tests (see the Proceedings).
The RM2 corpus was recorded at Texas Instruments. The NIST speech recognition scoring software originally distributed on the RM1 "Test" Disc was adapted for RM2 sentences and is included in this publication.
