The perceptual attunement to native vowel categories has been reported to occur at 6 months of age. However, some languages contrast vowels both in quality and in length, and whether and how the acquisition of spectral and duration-cued contrasts differs is uncertain. This study traced the development of infants' sensitivity to native (Czech) vowel-length and vowel-quality contrasts. The results suggest that in a vowel-length language, infants learn to categorize vowels in terms of length earlier and/or more robustly than in terms of quality, the representation of which may still be relatively underdeveloped at 10 months of age.
据报道，对母语元音类别的感知协调在6个月大时就已出现。然而，有些语言在元音的音质和时长方面都存在差异，而对频谱和时长线索差异的习得是否不同以及如何不同尚不确定。本研究追踪了婴儿对母语（捷克语）元音时长和元音音质差异的敏感度发展情况。结果表明，在一种元音时长语言中，婴儿学会根据时长对元音进行分类的时间比根据音质进行分类的时间更早和/或更稳固，而在10个月大时，婴儿对音质的表征可能仍相对不发达。
