Non-tone language infants' native language recognition is based first on supra-segmental then segmental cues, but this trajectory is unknown for tone-language infants. This study investigated non-tone (English) and tone (Thai) language 6- to 10-month-old infants' preference for English vs. Thai one-syllable words (containing segmental and tone…

Background and Aims: This longitudinal study investigated the language skills, phonological working memory and lexical-tone perception of Mandarin-speaking late-talkers (LTs) and those with typical language development (TLD) at 27 months, while also examining their connections with novel word-referent mapping (W-R mapping) through eye-tracking at…

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…

Purpose: The aim of this study was to explore when and how Mandarin-speaking children use contextual cues to normalize speech variability in perceiving lexical tones. Two different cognitive mechanisms underlying speech normalization (lower level acoustic normalization and higher level acoustic-phonemic normalization) were investigated through the…

The ability to map similar sounding words to different meanings alone is far from enough for successful speech processing. To overcome variability in the speech signal, young learners must also recognize words across surface variations. Previous studies have shown that infants at 14 months are able to use variations in word-internal cues (i.e.,…

Contrastive focus, conveyed by prosodic cues, marks important information. Studies have shown that 6-year-olds learning English and Japanese can use contrastive focus during online sentence comprehension: focus used in a "contrastive context" facilitates the identification of a target referent (speeding up processing), whereas focus used…

Purpose: Previous studies reported that children acquire Cantonese tones before 3 years of age, supporting the assumption in models of phonological development that suprasegmental features are acquired rapidly and early in children. Yet, recent research found a large disparity in the age of Cantonese tone acquisition. This study investigated…

Purpose: The purpose of this study was to determine whether the degree of dominance of Mandarin-English bilinguals' languages affects phonetic processing of tone content in their native language, Mandarin. Method: We tested 72 Mandarin-English bilingual college students with a range of language-dominance profiles in the 2 languages and ages of…

The purpose of the dissertation is to examine Mandarin-speaking children's acquisition of a syntax-dependent phonological rule Tone 3 Sandhi (T3S). A Tone 3 (low dipping tone) is changed to a Tone 2 (mid rising tone) when it is followed by another Tone 3. Application of T3S in fact involves a complex process. In setting up the prosodic domains…

Two studies explored the nature of phonological awareness (PA) in Chinese. In Study 1, involving 146 children, awareness of phoneme onset did not differ from chance levels at ages 3-5 years in preschool but increased to 70% correct in first grade, when children first received phonological coding (Pinyin) instruction. Similarly, tone awareness was…

A literature review pertaining to the teaching and learning of stress and intonation in native and second languages considers the functional movement, conversational English, the difficulty of learning stress/intonation, stress within words and sentences, difficulties for speakers of tone and syllable-timed languages, and tests of stress and…
