Accentual prominence has well-documented effects on various phonetic properties, including timing, vowel quality, amplitude, and pitch. These cues can exist in trading relationships and can differ in magnitude in different languages. Less is understood about how phonetic cues to accentuation surface under different phonological constraints, such as those posed by segmental phonology, aspects of the prosodic hierarchy, and intonational phonology. Dialectal comparisons offer a valuable window on these issues, because dialects of a language share basic aspects of structure and function, but can differ in key segmental and suprasegmental constraints which may affect the cues that realise accentual prominence. We compared the realisation of trochaic words (e.g. cheesy, picky) in accented/unaccented and phrase-final/non-final positions in two dialects of British English, Standard Southern British English, and Standard Scottish English as spoken in Glasgow. We found generally shallower prominence gradients for Glasgow than SSBE with respect to intensity and duration, and very little evidence of accentual lengthening of vowels in Glasgow, compared to robust effects in SSBE. In contrast, phrase-finality had similar effects across the two dialects. The differences observed illustrate how the expression of accentual prominence reflects and reveals the different segmental and intonational systems that operate within dialects of the same language.

突出的音调对各种语音特性（包括时间，元音质量，振幅和音高）都有有据可查的影响。这些提示可以存在于交易关系中，并且在不同的语言中其大小可能会有所不同。人们对在不同音系约束下，例如段音系，韵律层次和民族音系所带来的音调提示在重音表面上的表现了解得很少。方言比较为这些问题提供了一个宝贵的窗口，因为语言的方言具有结构和功能的基本方面，但是在关键的分段和超分段约束方面可能有所不同，这可能会影响实现重音的提示。我们比较了普通单词（例如俗气，挑剔）的实现）在格拉斯哥所说的两种英式英语，标准南部英式英语和标准苏格兰英语方言中的重音/未重音和词组最后/非最后的位置。我们发现，就强度和持续时间而言，格拉斯哥的凸出梯度通常比SSBE浅，与SSBE的鲁棒效应相比，格拉斯哥的元音突显变长的证据很少。相反，短语最终性在这两种方言中具有相似的作用。所观察到的差异说明了突出的表情表达如何反映和揭示在同一语言的方言中运作的不同的语段和民族系统。
