Tone hyperarticulation in Cantonese infant-directed speech

There is extensive evidence for vowel hyperarticulation in infant-directed speech (IDS) [1, 2, 3], but little is known about lexical tones in tonal IDS. Here, longitudinal recordings of Cantonese IDS revealed that tones, like vowels, are hyperarticulated. Implications of this finding for infant linguistic development are discussed.

Tone Hyperarticulation and Intonation in Cantonese Infant Directed Speech

Vowel hyperarticulation in infant-directed speech (IDS) has been found consistently across both tone (Mandarin [1]) and non-tone (Russian, Swedish, American [2] and Australian English [3]) languages and has been posited as a possible bootstrapping mechanism for early language development in infancy [1]. Here we investigated (1) IDS in Cantonese to examine whether tones, like vowels, are hyperar...

Vowels and tones in infant directed speech: hyperarticulation for both, but different developmental patterns

A number of studies have shown that mothers hyperarticulate vowels in their Infant Directed Speech to their 6-month-old infants. Here we investigate the possibility that such hyperarticulation might also occur for lexical tone for mother-infant dyads in tone language environments, and possible changes in mothers’ vowel and such tone hyperarticulation in IDS across the infant’s first year. IDS f...

EFL Conversational Triads: Foreigner-directed Speech and Hyperarticulation

The study examines interactions associated with foreignerdirected speech (FDS) within EFL triadic conversation exam where learners differ in outspokenness. The results showed that learners’ outspokenness affected foreign examiners’ vowel articulation. More vowels underwent distinct change across learners’ positive-coded utterances in F2, whereas in F1 the vowel change in the high-communicative ...
