我们研究了元音基频（f0）是否受地区差异的影响，目的是（1）确定元音高度和f0（“内在f0”）之间的关系如何在地区元音系统中得到利用;（2）确定语音环境对f0变化的影响在地区变体中是否存在差异。一组扩展的声学措施探讨了F0的元音在孤立的令牌（实验1）和连接语音（实验2）从36名妇女代表3种不同的品种的美国英语。区域差异被发现在孤立的令牌中的f0形状，在高低元音之间的固有的f0差异的大小，在强调元音的f0轮廓的性质，并在完成的f0轮廓的背景下，尾音发声。区域变体以不同的方式在元音中利用f0控制，包括区域f0范围和f0形状的变化。
We examined whether the fundamental frequency (f0) of vowels is influenced by regional variation, aiming to (1) establish how the relationship between vowel height and f0 (“intrinsic f0”) is utilized in regional vowel systems and (2) determine whether regional varieties differ in their implementation of the effects of phonetic context on f0 variations. An extended set of acoustic measures explored f0 in vowels in isolated tokens (experiment 1) and in connected speech (experiment 2) from 36 women representing 3 different varieties of American English. Regional differences were found in f0 shape in isolated tokens, in the magnitude of intrinsic f0 difference between high and low vowels, in the nature of f0 contours in stressed vowels, and in the completion of f0 contours in the context of coda voicing. Regional varieties utilize f0 control in vowels in different ways, including regional f0 ranges and variation in f0 shape.
