Introduction

SUSAS (Speech Under Simulated and Actual Stress) Transcripts was developed by the Linguistic Data Consotium and consists of transcribed English speech by helicopter pilots. The speech data in this release is a subset of the data in SUSAS (LDC99S78), created by the Robust Speech Processing Laboratory at the University of Colorado-Boulder under the direction of Professor John H. L. Hansen and sponsored by the Air Force Research Laboratory.

Data

The transcripts in this release cover several speech files in the SUSAS collection, specifically, speech from four Apache helicopter pilots. 

The SUSAS speech database is partitioned into four domains, encompassing a wide variety of stresses and emotions. A total of 32 speakers (13 female, 19 male), with ages ranging from 22 to 76 years, were employed to generate in excess of 16,000 utterances.

A common highly confusable vocabulary set of 35 aircraft communication words make up the database. All speech tokens were sampled using a 16-bit A/D converter at a sample rate of 8kHz.
