The current study examined Vowel Inherent Spectral Change (VISC) of English vowels spoken by English-, Chinese-, and Korean-native speakers. Two metrics, spectral distance (amount of spectral shift) and spectral angle (direction of spectral shift) of formant movement from the onset to the offset, were measured for 12 English monophthongs produced in a /hvd/ context. While Chinese speakers showed significantly greater spectral distances of vowels than English and Korean speakers, there was no significant speakers' native language effect on spectral angles. Comparisons to their native vowels for Chinese and Korean speakers suggest that VISC might be affected by language-specific phonological structure.
本研究考察了以英语、汉语和韩语为母语的说话者所发英语元音的元音固有频谱变化（VISC）。从起始到结束，通过测量共振峰运动的光谱距离（光谱移动量）和光谱角（光谱移动方向）这两个指标，对 12 个在/hvd/语境中产生的英语单元音进行了测量。虽然汉语说话者的元音光谱距离明显大于英语和韩语说话者，但元音的母语语言效应在光谱角上没有显著差异。对汉语和韩语说话者的母语元音进行比较后表明，VISC 可能受到语言特定语音结构的影响。
