Several experiments have found that changing the intrinsic f0 of a vowel can have an effect on perceived vowel quality. It has been suggested that these shifts may occur because f0 is involved in the specification of vowel quality in the same way as the formant frequencies. Another possibility is that f0 affects vowel quality indirectly, by changing a listener's assumptions about characteristics of a speaker who is likely to have uttered the vowel. In the experiment outlined here, participants were asked to listen to vowels differing in terms of f0 and their formant frequencies and report vowel quality and the apparent speaker's gender and size on a trial-by-trial basis. The results presented here suggest that f0 affects vowel quality mainly indirectly via its effects on the apparent-speaker characteristics; however, f0 may also have some residual direct effects on vowel quality. Furthermore, the formant frequencies were also found to have significant indirect effects on vowel quality by way of their strong influence on the apparent speaker.
多项实验发现，改变元音的固有频率会对感知到的元音质量产生影响。有人认为，这些变化可能是因为 f0 与共振峰频率一样，参与了元音质量的指定。另一种可能性是，f0 通过改变听者对可能发出该元音的说话者特征的假设，间接地影响元音质量。在本实验中，参与者被要求听在 f0 和共振峰频率方面不同的元音，并在每次试验中报告元音质量以及说话者的性别和体型。这里呈现的结果表明，f0 主要通过其对说话者特征的影响间接影响元音质量；然而，f0 也可能对元音质量有一些残余的直接影响。此外，共振峰频率也通过对说话者的强烈影响，对元音质量产生了显著的间接影响。
