This study examined the response of the respiratory system to 3 cues used to elicit increased vocal loudness to determine whether the effects of cueing, shown previously in sentence tasks, were present in connected speech tasks and to describe differences among tasks.
Fifteen young men and 15 young women produced a 2-paragraph reading passage in response to 4 different loudness cues: comfortable loudness level, targeting 10 dB above comfortable, at what they perceived as twice their comfortable loudness, and with multitalker noise present in the background. A short monologue was produced at comfortable loudness level and with noise in the background.
Differences in respiratory strategies were demonstrated for the different cueing conditions, similar to patterns observed in sentence productions. The kinematic patterns were similar for reading and monologue; however, utterances were longer and speaking rate was slower in the monologue task.
The findings extend the results from sentences to connected speech and provide support for the hypothesis that "intention" or goals play a role in the control of respiratory function during speech. Respiratory kinematics were similar across tasks, when the same cue was used, except for differences related to breath group length and speech rate.
本研究考察了呼吸系统对用于引发更大声量的3种提示的反应，以确定提示的效果（先前在句子任务中显示）是否存在于连贯言语任务中，并描述任务之间的差异。
15名年轻男性和15名年轻女性根据4种不同的声量提示朗读一篇两段式阅读文章：舒适声量水平、比舒适声量高10分贝、他们认为是舒适声量两倍的声量以及背景中有多人交谈噪音的情况。在舒适声量水平和背景中有噪音的情况下进行一段简短的独白。
不同提示条件下表现出呼吸策略的差异，类似于在句子产出中观察到的模式。朗读和独白的运动模式相似；然而，独白任务中的话语更长，语速更慢。
研究结果将句子研究的结果扩展到了连贯言语，并为“意图”或目标在言语过程中呼吸功能控制中起作用这一假设提供了支持。当使用相同提示时，除了与呼吸组长度和语速相关的差异外，各任务的呼吸运动学相似。
