One aim of our study is to discuss some of the relations of prosodic parameters to the speech production process, e.g. how speech intensity is related to the vocal tract filter and the voice source and the underlying aerodynamics. A specific problem of phonetic interest is the role of subglottal pressure and fundamental frequency as intensity determinants and their covariation in speech. Our speech analysis displays, incorporating perceptually scaled syllable prominence, are suitable for multilevel studies of speech parameters. A new intensity parameter, SPLH, related to sonority is introduced. In combination with the standard sound pressure level it provides information on the voice source spectral slope. In Swedish, high long stressed vowels approach a semi-closed target, and thus a sonority minimum, which suggests a motor component in prominence perception.
我们研究的一个目的是探讨韵律参数与言语产生过程的一些关系，例如语音强度如何与声道滤波器、声源以及潜在的空气动力学相关。一个语音学上感兴趣的具体问题是声门下压力和基频作为强度决定因素的作用以及它们在言语中的协变。我们结合感知尺度音节突出度的语音分析适用于语音参数的多层次研究。引入了一个与响度相关的新强度参数SPLH。与标准声压级相结合，它提供了有关声源频谱斜率的信息。在瑞典语中，高长重音元音接近一个半封闭目标，从而达到响度最小值，这表明在突出度感知中存在运动成分。
