Automatic speech recognition systems: effects of environmental stressors

Chris Baber, Jan Noyes

There are a number of types of environmental stressor which can have an adverse impact on the use of automatic speech recognition. In this paper, a systems approach to the problem is presented, in which the system comprises the human and the speech recognition device performing specific tasks in a defined environment. From this perspective, the locus of the effects of environmental stressors can be seen to be the interface between human and speech recognition device. This means that it is important to appreciate the effects of the stressors on both human performance and speech production, and the likely consequences of these effects for the efficiency of the speech recognition system.
