婴幼儿对母语音位范畴的习得依赖于其与语言社会的交互。本研究从计算建模的角度出发,通过建立语言习得模型,利用家长输入语语料,模拟婴幼儿在言语交互中习得母语音位范畴的过程。基于联结的模型网络结构,本研究观察了语音信息和语义信息在音位习得中的交互作用。模拟结果揭示出,婴幼儿母语音位感知的建立不是一个由单一因素所决定的过程,基于语义的由高层到底层的加工对形成正确的母语音位范畴感知起着至关重要的作用。
The acquisition of mother tongue phonemes in infants and toddlers depends on their interaction with the language community. From the perspective of computational modeling, this study uses the language of parental input to construct a model of language acquisition and simulates the process of infants’ acquisition of mother tongue phonemes in verbal interaction. Based on the connected model network structure, this study observes the interaction of phonetic information and semantic information in phoneme acquisition. The simulation results reveal that the establishment of mother tongue phoneme perception in infants and young children is not a process determined by a single factor. The processing from the top to the bottom based on semantics plays a crucial role in forming the correct mother tongue phoneme category perception.
