Interactive Communication -- cross-disciplinary perspectives from psychology, acoustics, and technology

Abstract

Interactive communication (IC), i.e., the reciprocal exchange of information between two or more interactive partners, is a fundamental part of human nature. As such, it has been studied across multiple scientific disciplines with different goals and methods. This article provides a cross-disciplinary and selective primer on contemporary IC integrating psychological mechanisms with speech signal, acoustic and media-technological constraints in theory, measurement, and applications. First, we outline theoretical frameworks that account for verbal, nonverbal, and multimodal aspects of IC, including distinctions between face-to-face and computer-mediated communication. Second, we summarize key methodological approaches, including behavioral, cognitive, and experiential measures of communicative synchrony and acoustic signal quality. Third, we discuss selected applications, applications in which speech transmission, signal enhancement, mediated dialogue, and real-time coordination are central, namely assistive listening technologies, conversational agents, and social VR, alongside ethical considerations. Taken together, this primer highlights how human capacities and technical systems jointly shape IC, consolidating concepts, findings, and challenges that have often been discussed in separate lines of research.
