Linking the discrimination of voice onset time (VOT) in infancy with infant language background, we examine the perceptual changes of two VOT contrasts (/b/-/p/ and /p(h)/-/p/) by Dutch monolingual and bilingual infants from 8 to 15 months of age. Results showed that language exposure and language dominance had a strong impact on monolingual and bilingual infant VOT perceptual patterns. In addition, perceptual turbulence was found at 8-9 months for bilingual infants, and stabilized perception was presented for all infants from 11 months onwards. We thus report a general input-driven developmental VOT perception in both monolingual and bilingual infants, with perceptual turbulence for bilinguals in the second half of the first year of life.
将婴儿期语音起始时间（VOT）的辨别与婴儿的语言背景联系起来，我们研究了8至15个月大的荷兰单语和双语婴儿对两种VOT对比（/b/-/p/和/p(h)/-/p/）的感知变化。结果表明，语言接触和语言优势对单语和双语婴儿的VOT感知模式有强烈影响。此外，双语婴儿在8至9个月时出现感知波动，11个月起所有婴儿的感知趋于稳定。因此，我们报告了单语和双语婴儿中普遍存在的由输入驱动的VOT感知发展情况，双语婴儿在生命的第一年下半年存在感知波动。
