Using a semi-spontaneous speech corpus, we present evidence from computational modelling of tonal productions from Mandarin-speaking children (4- to 11-years old) and adults, showing that children exceed the adult-level tonal distinction at the age of 7 to 8 years using F0 cues, but do not reach the high adult-level distinction using spectral cues…

Weak syllables in Germanic and Romance languages have been reported to be challenging for young children, with syllable omission and/or incomplete reduction persisting till age five. In Mandarin Chinese, neutral tone (T0) involves a weak syllable with varied pitch realizations across (preceding) tonal contexts and short duration. The present study…

This study investigates the pitch properties of infant-directed speech (IDS) specific to word-learning contexts in which mothers introduce unfamiliar words to children. Using a semi-spontaneous story-book telling task, we examined (1) whether mothers made distinctions between unfamiliar and familiar words with pitch in IDS compared to…

The current study examined five- and seven-year-old Mandarin-speaking children's processing of lexical tones in relation to speech segments by varying onset and rime in an oddity task (onset±rime±). Results showed that children experienced more difficulty in lexical tone oddity judgment when rimes differed across monosyllables (e.g.…

How do children develop the mapping between prosody and other levels of linguistic knowledge? This question has received considerable attention in child language research. In the present study two experiments were conducted to investigate four- to five-year-old Mandarin-speaking children's sensitivity to prosody in ambiguity resolution. Experiment…

Early prosodic development (f[subscript 0] variation) was systematically measured in Mandarin-learning infants at the transition from babbling to producing first words. Spontaneous vocalizations of twenty-four infants aged 0;7 to 1;6 were recorded in 45-minute sessions. The speech production of twenty-four caregivers was also audio-recorded during…

This study used three experiments to study whether infant-directed (ID) or adult-directed (AD) speech facilitated the learning of Chinese vocabulary by adults whose native language was English and who had had no prior knowledge of Chinese. Results indicate that ID speech may play a pivotal role in early lexical acquisition. (51 references)…
