Abstract

In this chapter, we consider a range of issues associated with analysis, modeling, and recognition of speech under stress. We start by defining stress, what could be perceived as stress, and how it affects the speech production system. In the discussion that follows, we explore how individuals differ in their perception of stress, and hence understand the cues associated with perceiving stress. Having considered the domains of stress, areas for speech analysis under stress, we shift to the development of algorithms to estimate, classify or distinguish different stress conditions. We will then conclude with revealing what might be in store for understanding stress, and the development of techniques to overcome the effects of stress for speech recognition and human-computer interactive systems.
