Forthcoming: Speech during exercise: Adaptation and variability in production

Much of human communication occurs while people are moving, exerting themselves, or otherwise not at rest, yet speech production in such contexts has received little systematic attention. Previous studies have typically addressed respiration, phonation, or articulation separately, making it difficult to characterize changes in speech production as a whole. This book presents a multi-level investigation of speech during controlled physical activity. Combining respiratory data, acoustic analysis, and speaker reports, it examines how different exercise levels affect breathing patterns, phonation, and articulatory realization. The analyses reveal adjustments across all production levels, but no uniform production mode: speakers show distinct patterns of response under the same physical workload. By integrating quantitative and qualitative evidence, the book highlights the role of between-speaker variability for understanding speech behavior under real-life conditions. The findings inform models of speech production and variability, and they support a broader view of speech as a dynamically coordinated system that adapts across changing bodily states.
