在这项研究中,我们探讨了重点背景结构的影响,重音(即一个字是否具有音高重音或不)和喉上关节,声学持续时间(音节和足持续时间)和嘴唇运动学(参数有关的开放姿态:持续时间,位移,峰值速度和刚度)。虽然重点的话是重音和那些焦点之外的话没有,有口音的话,当他们在广泛的焦点上下文和非重音的目标词(焦点之外)之间的差异很少。因此,加重本身似乎并不导致喉上的修改。然而,在广泛焦点和对比焦点中,词语的喉上清晰度有明显的区别。我们的结论是,喉上关节-在声学持续时间和嘴唇运动学-直接相关的焦点结构和对比度的表达,并没有,相反,在以前的研究中得出的结论,介导的存在或不存在的口音。
In this study we explore the effects of focus-background structure on accentuation (i.e. whether a word bears a pitch accent or not) and supralaryngeal articulation, measured in terms of acoustic durations (syllable and foot durations) and lip kinematics (parameters relating to the opening gesture: duration, displacement, peak velocity and stiffness). Although words in focus were accented and those out of focus were not, there were few supralaryngeal differences between accented words when they were produced in the broad focus context and unaccented target words (out of focus). Thus, accentuation per se did not appear to lead to supralaryngeal modifications. However, there was a clear distinction between the supralaryngeal articulation of words in broad focus and those in contrastive focus. We conclude that supralaryngeal articulation – in terms of acoustic duration and lip kinematics – is related directly to the expression of focus structure and contrastivity, and is not, contrary to conclusions drawn in previous studies, mediated by the presence or absence of accent.
