Prenatal Music Exposure to Enhance Postnatal Language Development

The goal of this randomized controlled study is to evaluate the effect of prenatal music exposure on infants through two years of age. The study addresses two primary questions: * Whether prenatal music exposure enhances neural encoding of speech and improve language and cognitive outcomes during the first two years of life among fetuses * Whether predictive models can be developed from available fetal data to forecast individual differences in developmental outcomes among fetuses exposed to prenatal music. Participants will engage in music listening or self-learning five days a week until delivery. After the participants give birth, the children will be followed up on their neural responses to speech, as well as their language and cognitive development, until they reach two years of age. The investigators will compare the effects of low- and high-dose prenatal music exposure with a
