本文对美国英语半元音的声学特性进行了量化和统计分析。这些特征可分为区分半元音与其他语音的特征和区分半元音的特征。感兴趣的特征是响亮的，音节，辅音，高，后，前，卷舌。声学相关的这些功能进行了调查，在这项研究的半元音。声学相关性，这是基于相对的措施，进行了测试的语料库233多音节的话，其中每一个都是由两名男性和两名女性发言一次。在大多数情况下，适当的区别是由选择的声学特性的功能。然而，对于每一个属性，在被区分的声音的特征的声学相关性中有一些重叠。在重叠区域的声音的检查显示，其表面表现形式从规范形式有很大的不同。在很大程度上，观察到的变化可以解释的变化，由于功能扩展和减弱。
Acoustic properties related to the linguistic features which characterize the semivowels in American English were quantified and analyzed statistically. The features can be divided into those which separate the semivowels from other sounds and those which distinguish among the semivowels. The features of interest are sonorant, syllabic, consonantal, high, back, front, and retroflex. Acoustic correlates of these features were investigated in this study of the semivowels. The acoustic correlates, which are based on relative measures, were tested on a corpus of 233 polysyllabic words, each of which was spoken once by two males and two females. For the most part, the appropriate distinctions are made by the chosen acoustic properties for features. However, for each property, there was some overlap in the acoustic correlates of features for the sounds being distinguished. An examination of the sounds in the overlap regions reveals that their surface manifestation varies substantially from the canonical form. In large part, the observed variability can be explained in terms of changes due to feature spreading and lenition.
