Introduction

Speech Under Simulated and Actual Stress (SUSAS) was 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 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.

SUSAS also contains several longer speech files from four Apache helicopter pilots. Those helicopter speech files were transcribed by the Linguistic Data Consortium and are available in SUSAS Transcripts (LDC99T33).

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.
