婴儿感知母语和非母语语音对比能力的早期变化通常归因于他们对语音类别的发展知识。我们批判性地研究这一假设，并认为，有一点直接的证据类别的知识在婴儿期。然后，我们提出了另一种解释，即婴儿的感知发生变化，因为他们正在学习一个适合代表语音的感知空间，而不是将该空间划分为语音类别。如果正确的话，这个新的解释对于理解早期语言发展有着重要的意义。
Early changes in infants’ ability to perceive native and nonnative speech sound contrasts are typically attributed to their developing knowledge of phonetic categories. We critically examine this hypothesis and argue that there is little direct evidence of category knowledge in infancy. We then propose an alternative account in which infants’ perception changes because they are learning a perceptual space that is appropriate to represent speech, without yet carving up that space into phonetic categories. If correct, this new account has substantial implications for understanding early language development.
