体力活动会导致与休息状态截然不同的呼吸行为，从而影响言语产生。语音参数究竟是如何受到体力活动影响的，在很大程度上还不得而知。因此，我们研究了几个韵律参数在体力活动的影响下是如何变化的，并将重点放在了以前没有详细讨论的时间和呼吸特征上。研究人员分析了受试者在跑步机跑步练习前后朗读课文的语音，以了解跑步前后的韵律差异。最重要的发现包括更高的清晰度，更长的平均停顿和呼吸持续时间，更高的吸气强度，更高的呼气率，以及在剧烈跑步机跑步后立即记录的语音的平均F0更高。这些发现提供了对语音特征如何受体力影响的基本见解，并可能有助于推进语音中身体压力的自动分类。
Physical activity leads to a respiratory behaviour that is very different to a resting state and that influences speech production. How speech parameters are exactly affected by physical activity remains largely unknown. Hence, we investigated how several prosodic parameters change under influence of physical activity and focused on temporal and breathing characteristics which have not been addressed in detail before. Speech from subjects reading aloud a text before and after a treadmill running exercise was analysed for prosodic differences between before and after running. The most important findings include a higher articulation rate, longer averaged pause and breath durations, a higher in-breath intensity, a higher out-breath rate, and a higher mean F0 for speech recorded immediately after vigorous treadmill running. These findings provide fundamental insights into how speech characteristics are affected by physical effort, and may help advance automatic classification of physical stress in speech.
