Prenatal infant-directed speech: vowels and voice quality
Original language description
Speech addressed to young children is typically characterised by distinct acoustic properties. Here we describe infant-directed speech (IDS) addressed to unborn infants. Recordings of pregnant women (speaking Czech) show that prenatal IDS differs from adult-directed speech (ADS) in several vocalic properties. Compared to ADS, prenatal IDS has longer vowels (due to slower speaking rate) with short-long contrasts being preserved. The F1–F2 vowel space is larger in prenatal IDS than in ADS, the vowel-space expansion towards the periphery evokes enhancement of phonemic contrasts. Although overall pitch is not found to differ between styles, in IDS, F0 serves as a supporting cue to short-long contrasts. Voice quality is breathier in IDS than in ADS indicating intimacy or affection. Our results align well with previous findings for 'postnatal' IDS across languages and demonstrate that a distinct infant-directed speech style exists already before birth.
