检查五个声学参数（F0, F1, F2，音段持续时间和强度）可以比较婴儿定向语音（IDS），超语音和伦巴第反射。这些现象通常是单独研究的，每个现象都有一个或两个声学特征（例如，伦巴第语的强度）。本实验由两部分组成，研究了牙买加克里奥尔语和牙买加英语使用者的内言和外言差异。IDS和Lombard speech在F0和强度两个参数上的调整相似，IDS和Citation speech的频谱差异最大。这一结果很重要，因为它表明，虽然一个或两个声学参数可能是一种夸张言语的关键特征，但任务产生涉及一组复杂的连续声学参数的系统调整。综上所述，这里研究的扰动类型的声学结果允许沿连续体安排任务。这些调整类似于社会语音学研究中关于“风格转换”的社会语言学标记的操作模式。我们认为，这两种现象可以在建立在听众设计的社会语言学概念基础上的说话者内部变异的统一解释下进行处理。
Examination of five acoustic parameters (F0, F1, F2, segmental duration, and intensity) allowed comparison of Infant-Directed Speech (IDS), Hyperspeech, and the Lombard reflex. These phenomena have typically been investigated separately, each characterized in terms of one or two acoustic features (e.g., intensity for Lombard speech). The present two-part experiment examined intraspeaker and interspeaker variability in speakers of Jamaican Creole and Jamaican English. IDS and Lombard speech showed similar adjustments in two parameters (F0 and intensity), and IDS and Citation speech showed the greatest spectral differences. This result is important because it shows that while one or two acoustic parameters may be crucial characteristics of a type of exaggerated speech, task production involved the systematic adjustment of a complex set of continuous acoustic parameters. Taken together, the acoustic outcomes for the types of perturbations investigated here allow the tasks to be arranged along a continuum. These adjustments resemble patterns associated with the manipulation of sociolinguistic markers reported in sociophonetic studies of “style-shifting.” We argue that the two phenomena may be treated under a unified account of intraspeaker variability that builds upon the sociolinguistic concept of Audience Design.
