本研究探讨了德语阅读任务中的韵律规划问题。我们分析了即将到来的句子的发音长度和句法复杂性对两个声学参数(停顿时间和初始基频峰值)和两个呼吸参数(吸气深度和吸气持续时间)的影响。本研究共进行了两个实验，第一个实验记录了12名母语为德语的人的数据。他们阅读的句子在长度(短，长)和句法复杂性(简单，复杂)方面各不相同。根据四个语音参数对数据进行分析。停顿时间、吸气深度和吸气时间在句子长度上存在显著差异，但在句法复杂性上没有显著差异。在第二个实验中，假设初始f0峰只对第一个成分的长度操纵敏感。20名说话者被记录了第一个句法成分(短、中、长)和最后一个句法成分(短、长)的长度不同的朗读话语。初始f0峰的结果证实了我们的假设。结果表明，呼吸参数和停顿时长是下一个句子的整体规划参数，而基频峰值高度是对第一个成分的长度比较敏感的局部性指标。(C)2012爱思唯尔有限公司。保留所有权利。
This study investigates prosodic planning in a reading task in German. We analyse how the utterance length and syntactic complexity of an upcoming sentence affect two acoustic parameters (pause duration and the initial fundamental frequency peak) and two respiratory parameters (inhalation depth and inhalation duration). Two experiments were carried out.In the first experiment, data for twelve native speakers of German were recorded. They read sentences varying in length (short, long) and syntactic complexity (simple, complex). Data were analysed on the basis of the four phonetic parameters. Pause duration, inhalation depth and inhalation duration showed significant differences with respect to sentence length, but not to syntactic complexity. The initial f0 peak was not influenced by variations in length or syntactic complexity.In the second experiment it was hypothesized that the initial f0 peak is only sensitive to length manipulations of the first constituent. Twenty speakers were recorded reading utterances varying in the length of the first (short, medium, long) and last syntactic constituent (short, long). Results for the initial f0 peak confirmed our hypothesis. It is concluded that the breathing parameters and pause duration are global parameters for planning of the upcoming sentence whereas the height of the fundamental frequency peak is a more local measure sensitive to the length of the first constituent.
