This paper reports on an investigation of how the phonological
rule of the complementary relationship between vowel and
consonant duration is manifested in Swedish infant-directed
speech (IDS), as compared to adult-directed speech (ADS).
Cross-linguistic investigations indicate that vowels tend to be
prolonged in speech directed to infants. In contrast, there are
signs that consonants may be shortened in this speech style.
How then, would these tendencies affect the phonological rule
of V:C and VC: sequences in IDS?
Analysis of vowel and consonant durations in disyllabic content words from six Swedish mothers' IDS and ADS revealed that the VC proportionality is preserved in the IDS. The results suggest that important information of the linguistic structure of the ambient language is maintained.
The results are discussed from an infant developmental perspective in a model of IDS transforms.
