Effects of emotional and perceptual-motor stress on a voice recognition system's accuracy: An applied investigation

Abstract

This was an applied investigation examining the ability of a speech recognition system to recognize speakers' inputs when the speakers were under different stress levels. Subjects were asked to speak to a voice recognition system under three conditions: 1) Normal office environment, 2) Emotional Stress and 3) Perceptual-Motor Stress. Results indicate a definite relationship between voice recognition system performance and the type of low stress reference patterns used to achieve recognition. (Author)
