Abstract
Technological developments in automatic speech recognition (ASR) technology over the last couple of decades have resulted in ASR being considered for use in an ever-increasing number of applications. However, a number of physical and psychological environments are still deemed inappropriate for this technology. Several of the stressors creating adverse environments are considered here, in conjunction with their effects on human speech production, human performance in general, and the implications for ASR system design. We propose that a combination of continuing technological developments, together with the application of system engineering and human factors, will lead to ensuring the attainment of robust ASR performance in a number of environments previously considered as high risk.
