Child multilingual phonological errors are under-explored. Cross-linguistic studies suggest monolingual children make phonological errors that are subject to effects of language universality and ambient language characteristics. Bilingual Chinese children were observed to use not only typical, but also atypical phonological errors compared to monolingual peers acquiring similar languages. Atypical errors are a result of specific bilingual pair effects. Close-language-relatedness (Cantonese-Mandarin) is claimed to be responsible for the nonexistence of atypical errors in both languages, whilst distant-language-relatedness (Cantonese-English) is observed to cause atypical errors in both languages. The present novel cross-sectional study investigated phonological acquisition in three typologically distant languages: English-Mandarin-Malay by 64 multilingual Chinese children aged 2½-4½. The present research aimed to explore if multilingual Chinese children exhibit phonological errors which commensurate to that of monolingual and bilingual Chinese children acquiring similar languages as described in the literature. The single-word phonological test results revealed that the multilinguals exhibited typical and atypical phonological patterns which largely commensurate with the monolinguals and bilinguals. Similar to bilingual children, the multilingual children showed more atypical errors in English than in Mandarin, demonstrating effects of individual language irrespective of potential interaction with additional languages. The present result did not fully support the link between closeness in typology of languages and the absence of atypical errors. Rare atypical errors were found in Mandarin and Malay, two typologically different languages, and both were also interacting with English, another typologically different language. The present findings provided useful preliminary multilingual speech norms for the use of speech therapists.

Early child multilingual acquisition is under-explored. Using a cross-sectional study approach, the present research investigates the rate of multilingual phonological acquisition of English-Mandarin-Malay by 64 ethnic Chinese children aged 2;06-4;05 in Malaysia--a multiracial-multilingual country of Asia. The aims of the study are to provide clinical norms for speech development in the multilingual children and to compare multilingual acquisition with monolingual and bilingual acquisition. An innovative multilingual phonological test which adopts well-defined scoring criteria drawing upon local accents of English, Mandarin and Malay is proposed and described in this article. This procedure has been neglected in the few existing Chinese bilingual phonological acquisition studies resulting in peculiar findings. The multilingual children show comparable phonological acquisition milestones to that of monolingual and bilingual peers acquiring the same languages. The implications of the present results are discussed. The present findings contribute to the development of models and theories of child multilingual acquisition.

This study was designed to develop language-specific stimuli for the assessment of resonance and to obtain nasalance scores using the newly developed speech stimuli in Mandarin. Gender and age influences on nasalance scores for each of the stimulus were also examined. Participants recruited were typically developing Mandarin-speaking ethnic Chinese children aged 6;00-7;11 growing up in Malaysia. Perceptual ratings of nasality were made based on the GOS.SP.ASS.'98 (revised) for children while nasalance scores were recorded for each stimulus using the Nasometer II (Model 6400). Fifty Mandarin-speaking children (24 males and 26 females) were recruited. None of the participants were perceived with abnormal nasality on the three stimuli. The mean nasalance scores for the Mandarin stimuli were 16.08% (SD = 2.57, 95% CI = 15.35-16.81) for the Oral passage, 25.20% (SD = 3.63, 95% CI = 24.17-26.23) for the Oral-Nasal passage and 55.44% (SD = 4.17, 95% CI = 54.25-56.63) for the Nasal passage. No significant age- and gender-related differences were observed for all the three stimuli. This is the first set of Mandarin stimuli and nasalance norms for Mandarin-speaking children in Malaysia. The influence of phonetic content on nasalance is supported. Findings call for language-specific normative nasalance data and careful selection of stimuli for the assessment of resonance.
Development of the Mandarin Nonsense Word Identification Test

OBJECTIVE: This study aimed to develop a digitised Mandarin Nonsense Word Speech Perception Test for use in Malaysia, a multilingual country in Southeast Asia.
DESIGN: In Phase I, 400 vowel-consonant-vowel (VCV) nonsense word samples containing 20 Mandarin consonants in /a/, /i/, or /u/ contexts were recorded from two speakers of different genders. Acoustic analyses, sound quality ratings, and item validations were used to guide selection of items to form two gender-specific test lists. In Phase II, performance-intensity functions and test-retest reliability for the lists were established.
STUDY SAMPLE: Native Mandarin-speaking adults with normal hearing participated in Phase I (n = 10) and Phase II (n = 69).
RESULTS: Eighty-four of the 400 VCV words were selected to form two gender-specific test lists. A two-way repeated measure ANOVA revealed a significant interaction effect between speaker-gender and presentation level [F (4.88, 283.20) = 22.79, p
