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.
我们研究了元音的基频（f0）是否受地域差异的影响，旨在（1）确定元音高度与f0（“固有f0”）之间的关系在地域元音系统中是如何被运用的，以及（2）确定不同地域变体在语音语境对f0变化的影响的实现方式上是否存在差异。一组扩展的声学测量方法探究了来自代表三种不同美国英语变体的36名女性的孤立语音样本（实验1）和连贯语音（实验2）中元音的f0。在孤立语音样本的f0形状、高低元音之间固有f0差异的大小、重读元音的f0轮廓特征以及在韵尾浊音语境中f0轮廓的完成情况方面发现了地域差异。不同地域变体以不同方式运用元音中的f0控制，包括地域f0范围和f0形状的变化。
