| Summary: | The current study will examine the acoustic properties of infant-directed speech (IDS) to 8-month-old Norwegian infants, and will assess whether these properties, or the (articulatory) adaptation that parents make when speaking IDS as compared to adult-directed speech (ADS), i.e., the acoustic differences between the two registers, are related to infants' emerging language, as indexed by both parent report (CDI) and an eye-tracking experiment (IPL) of word comprehension. In a previous study with 18-month-old toddlers in Northern Norway, Rosslund et al. (2021) found that IDS is characterized by increased pitch, pitch range and vowel duration, as well as vowel space expansion, yet, more variable vowel categories. It was also found that parents' hyper-pitch, and low vowel category variability in IDS, was associated with expressive vocabulary size. The current study aims to assess the same properties of Norwegian IDS as in the previous study (Rosslund et al., 2021), directed this time to 8-month-old infants ... |
