Changes in speech and breathing rate while speaking and biking

International audienceSpeech communication is embedded in many daily activities. In this paper we investigate the effect of biking on respiratory and speech parameters. Breathing and speech production were recorded in eleven subjects while speaking alone and while speaking and biking with different rates. Breathing frequency, speaking rate, speech and pause intervals, overall intensity and f0 were analyzed for the different tasks. It was hypothesized that cyclical motion increases breathing frequency, which leads to a restructuring of speech and pause intervals or an increase in speech rate. Our results generally confirm these predictions and are of relevance for applied sciences

Multi‐speaker experimental designs: Methodological considerations

Research on language use has become increasingly interested in the multimodal and interactional aspects of language – theoretical models of dialogue, such as the Communication Accommodation Theory and the Interactive Alignment Model are examples of this. In addition, researchers have started to give more consideration to the relationship between physiological processes and language use. This article aims to contribute to the advancement in studies of physiological and/or multimodal language use in naturalistic settings. It does so by providing methodological recommendations for such multi-speaker experimental designs. It covers the topics of (a) speaker preparation and logistics, (b) experimental tasks and (c) data synchronisation and post-processing. The types of data that will be considered in further detail include audio and video, electroencephalography, respiratory data and electromagnetic articulography. This overview with recommendations is based on the answers to a questionnaire that was sent amongst the members of the Horizon 2020 research network ‘Conversational Brains’, several researchers in the field and interviews with three additional experts.H2020 Marie Skłodowska‐Curie Actions http://dx.doi.org/10.13039/100010665Peer Reviewe
